New Tank

[muddyfox]

Hi,

A really good friend of mine is giving up fishkeeping and has offered
to pass on his 120 litre (30 US Gal / 25 Imp Gal) tank. I've been
wondering what to put into it. These are my ideas:

(1) Small tiger barb community: 8 tiger barbs, 4 swordtails, 1
red-finned shark (or, as a variation on this could have 10 smaller
barbs (say pentazona's or cherry barbs), 5 swordtails and 1 red-finned
shark.)
(2) Freshwater planted Angel tank - say 6 fish
(3) Peaceful community tank: Guppy's, neons, platys, corys

Any comments, ideas, suggestions would be great.

Thanks

Muddy.


(PS: My water is pretty hard here, so I'm not sure if I can keep
angels - I would always go for tank bred stock rather than wild caught
fish because I know they're more tolerant, but my pH tends to sit
around 8.0 which really is quite high for fish like this and I would
like whatever fish I keep to be thriving rather than surviving. I do
love angels though. I've always wanted a species tank.)

Ah, so that must be why you pick fish that like soft water? :-)

What about hard water fish? African cichlids? Monos, scats, archers, puffers?
(they prefer bit of salt).

If it were me I'd add one Endlers female, feed it well and stand back.

I ahve a similar tank with one angel, one red fin shark, a cory, pleco,
and a few assorted tetras also I started out with 6 guppies, last count
makes it 20+, hopefully they will self limit themselves or the angel
will do it for them.

Apart from livebearers, angels and barbs are the only other fish I know
much about keeping. I guess I'm really sticking with what I know.

I did look at cichlids but I can't see myself keeping them. Partly
this is because my reading suggests that they are harder to keep and
I'm just getting back into fishkeeping after a more than ten years away
from it so I figure I'll do some easier tanks first and partly because
I've heard nothing but bad things about their aggressive, territorial
behaviour. I know barbs, esp Tigers, get a bad press, but in a good
sized shoal with lots of swimming room and tank mates they can't bully
they seem fine.

My impression of cichlid tanks is that they are like a war zone and
little can be done to stop it. I can't seem to type the word 'cichlid'
into a search engine without hearing 'this fish ate this fish and keeps
the rest in terror' type stories. Maybe you only hear about the
disasters created through inexperience and lack of proper knowledge but
it doesn't encourage me at all. I suspect that I have quite a
jaundiced view of what can be a very beautiful group of fish.

I do like the look of some of the Monodactylus spp, particualrly M.
sebae, but the nearest I've come to a brackish tank is to add some
aquarium salt for black mollies. How do you look after a fully
brackish setup? Do you need all the kit for marine - protien skimmer,
RO unit, sal****er mix (watered down), UV steriliser etc etc. or is
brackish more like tropical with aquarium salt added and GH and KH
monitered? I don't really like puffers or archers much although scats
are OK.

Well, I have always had a soft spot for guppy's and I do love the tiny
little fry. I've usually ended up with too many though. They would
look georgeous - lots of them in a nice sized tank.

Thanks ever so much for your ideas. I was really hoping the more
experienced folk here would be able to open my eyes to new
possibilities which is exactly what you've done!

Thanks,

Muddy

PS: I know angels are cichlids too but they seems lot easier to keep
and not really territorial at all when not breeding. :)

Cool. Endler's I mean. 30 gallons would be a pretty snug fit for 6
angels.

Afrcans are esier to keep than angels IMO.

I don't keep cichlids but a lot of my friends do. The problems with
uneven agression apparanly stem from mixing africans from different
lakes. Stick to one lake and you're ok.

My favorite tank for years had one species of Cryptocoryne and Endlers
and that's it. Both took off like mad and there were hundreds of each.

Google tropical fish and you will learn a lot about what's out there and
their water preferences. With our hard alkaline water I bypass all the fish
I know wont thrive in my tanks. I'm surprised Bettas live as long as they
do for me.

I should put my flame retardant suit on before saying this but I AGREE with
you about cichlids. Also I don't find the south American cichlids all that
attractive and they get large. The Malawi (African) cichilds are much more
colorful and only a little less aggressive. Some of those also get large.

No, not for a braskish tank. But many plants will not survive in brackish
water.

The problem I had with guppies is the age-old overpopulation to where none
grow out to a normal size. Then what do you do with them? The stores want
large guppies and don't take the small ones....... and once overcrowded you
need to do constant gravel vacuuming and water changes - sometimes 2 or 3
times a week. I think you can see how I ended up with mostly goldfish and
koi.

Google around or pick up a good book on tropical fish from your LFS. Bone
up on what does well in your water, make a list and go from there. :-)

==================
The problem with angels is once they start to breed they continue on and you
have to remove all the other fish or you have a war zone in your tank. Been
there. Done that several times. Angels don't stay small for long. They
were always one of my favorite tropical fish. But every time a pair started
to breed I either had to remove the pair and return them to the LFS or
remove all the other fish being harassed by them. It's something to think
about......

Plant heavily. When I had an all guppy tank, their pretty bloodlines
got more and more diluted, or concentrated, not sure which, but after
a year or so each new spawn brought drabber and drabber babies.
However, that hasn't prevented me from planning another similar tank
for the near future.

What I have learned from RAFM:
Filling a large tank with plants and one species of smallish fish to
capacity. There are so many kinds of fish that don't do much for me,
until you add 30 or 40 or more to a single species tank. I think
Gill's species tank of Blue Eyed Gertrudes got me thinking along those
lines. Your own mention of all tiger barbs sounds great.

You're right, I've read about problems with breeding pairs - for some
reason I'd assumed there would be no breeding (bad assumption where
living things are concerned :-o ). Apparently in the wild they all
disappear off into the flooded forest during the wet season and breed
in pairs away from each other. They are highly terratorial during this
period. Then, breeding over, they return to the main river as the
water goes down and shoal together again. Maybe, if I _really_ want
angels I could just keep a pair in my 60 litre planted tank. It will
have much softer water because I'm using ADA Aquasoil and should they
choose to breed they will not be grumpy with other tank mates.
Although, if I did this I'd probably like to put a small oto or a
shrimp or two in the tank, if I could do thjat without trouble. I'd
have to be prepared to deal with the fry too should they spawn. Could
be quite exciting!

Thanks for your thoughts - very helpful, as usual :)

Did anyone read that this is a 30 gallon tank??? Scats grow to 12" and
require full marine conditions in adulthood. There's no way to house
those fish long-term in a 30 gallon tank. Monos are not much better,
since they grow to 8" and are very active swimmers. Sebae monos can
reach a foot tall in good conditions. Maybe, just maybe, you could get
away with a fully grown archer in that tank.

Rainbowfish from the Glossolepis, Melanotaenia, and Telmatherina genuses
(includes celebes, boseman's, turquoise, and New Guinea red) require
hard water. Threadfins do OK in hard water too. Raunbows are easy to
keep and much more peaceful than African cichlids. Some species get as
large as 5", so be sure you have space for the adults.

Tiger barbs get bad press because they're nippy little SOBs. Put them
in a species tank, or forget about them. If you put them in with
swordtails like you were suggesting, the swords will be constantly damaged.

> Afrcans are esier to keep than angels IMO.

African are amazingly hardy fish. Angels are hardy too, if you find
good ones. Problem is, your typical $3 angel is not healthy while a $1
"assorted African cichlid" will be fine.

....until they pair up, start breeding, and beat the snot outta anything
that moves. I kept a Tanganyikan tank with one pair of open-water
Malawi haps (they didn't fight for rock space so they were fine) and
still lost fish at first. However, that tank settled down once all the
fish found their territory. I had three different species of fish
breeding at the same time in that tank. In fact, I'd take a tank full
of African cichlids over a shoal of tiger barbs any day.

The worst cichlid tales are from the big South American cichlids rather
than Africans. Those fish are big and psychotic.

Read comments on adult sizes of monos and scats above. To run a full
brackish setup, you use sal****er mix and monitor salinity with a
hydrometer. SG should be around 1.011. The high alkalinity and pH
means ammonia is very toxic so stocking should be lower than in
freshwater. You need good wet/dry or biowheel filtration, but UV, RO
and a skimmer are not necessary.

Or you can start off with a few freshwater angelfish and after they
pair off and get territorial and begin to get into scraps with each
other, the resulting fish will look like Monos. Best off both worlds.

Somepeople think if you have enough Tigers in the tank they wont bother the
other fish - WRONG! I scratched them off my list long ago.

Some Africans will beat the snot out of anything that moves even when
they're not breeding. They take over part of the tank and that's that.
Rearrange the rocks and in less than 48 hours they have another part staked
out. And they sometimes gang-up on another tankmate and tear it to shreds.
Been there - got home just in time to save my Rusty back in 1999. For now
they're also off my "fish to keep" list.

So are some of the Malawi's once they reach a good size. :-(

I noticed that some stores like PetsMart now have stickers on all their
tanks giving the adult size and diet of the fish they sell. I don't think
most people realize how LARGE some fish get.

My fancy guppies just die off one by one - which is why I am going to write
my next message on this newsgroup. Warning - I recommend no one depends on
live bearers being self-regulating because they aren't (at the very least
not if you want your other types of fish that are in the same tank to not be

===========================
No, they're not self regulating. I didn't have problems with nitrites but
did have problems with perhaps hormones that stunted their growth. I
couldn't find any LFSs at the time to take any but the LARGEST most salable
guppies. After unloading those I was stuck with a mess of small unsalabe
fish..... finally I gave every single one to someone I knew with a 30L
tank. She put them in a community tank and in months had no guppies at all.
Those were the last guppies I had.

You may need more filtration (bigger filter, second filter etc.) on your
tank if you're seeing nitrites.

Yes, I've got three books and I spend a tonne of time on the internet
looking up fish too but the biggest problem I seem to have with
research into this area generally is that the books don't agree with
each other. One will say such and such a fish is OK from pH 6.5 to pH
7.8 and another will say they need soft acid water (which doesn't agree
with pH 7.8!) and another will say suitable for any water type! It
drives me crazy. The same disparity in data is all over the internet
too. How do you find a reliable source of information? What do you
guys read to get decent fish info? Can you recommend a good website or
book with data I can trust?

Ho hum. Thanks! :)

Yes, the Tiger barbs are lovely fish. Could I put a couple of small
otos or loaches with the barbs, just to keep the algae down a bit? Or
would they get nipped to pieces?

I agree with you about conflicting information. As a general rule of
thumb I tend to look at what my LFS has in stock and watch the fish over
a few weeks to see that they have acclimitized to the water conditions.
Two places I go to use much the same tap water as me - you can usually
ask this as well and get an accurate answer if it is a good place. This
newsgroup is quite a good place to ask if you are not sure. When I do
google searches I tend to look at more than one site and take the
majority view - so if 5 out of 6 sites say hard water and one doesn't I
take it that the fish are best suited to hard water (not perfect but as
good as I can come up with). Another good source (you're in the UK
aren't you from your ISP?) are magazines - Practical Fish Keeping (PFK)
is a good one - they also carry a lot of the info on their website after
it has been published.

An example came up today, in fact. Rams are generally best suited to
lower pH and softer water than we have locally. I'm just back from the
LFS where they had 3 tankfuls of Rams - really pretty little fish (I've
got one at the moment). I started discussing them (as I want some more
but am not ready for them yet) and was advised to give them at least
another week in the shop before even considering buying them because of
the water thing.

When it comes to water type IMO (with some notable exceptions such as
Discus (soft), Mbunas(hard)) some fish will acclimatise to harder/softer
water. It also depends where they are bred - if they were bred in hard
water you are in with a better chance. Also make sure that you
acclimatise them to your actual tank water when you add them by slowly
mixing the tank water into the bag containing the fish. Also bear in
mind that some fish do better if the tank is more mature - for example I
wouldn't put Clown Loaches into a new tank (even if I'd seeded it) for
quite a few weeks.

Like you, I'm tempted by Barbs (I like the green ones) but haven't added
any yet. I've heard that if you keep them in a group of 6 or more then
the fin nipping issue becomes less. I still wouldn't keep them with
long-finned fish (although ironically you can now get long-finned barbs).

Rainbows are great fish. Be careful as some are not suited to hard water
(my LFS advises against Thread Fins without intervening to soften the
water).

I have some Red Rainbows, Boesman Rainbows and some (well rather a lot
of) dinky Blue Eyed Gertrude Rainbows. One thing to bear in mind is that
most of the rainbows (especially the Reds and the Boesmans) do not get
their full colour for some time (up to a year even) but once they do
they are spectacular - one of my Reds and one of my Boesmans are getting
their adult colouration right now (I have had them since September last
year). So when you see them in the shop they are generally quite drab
and you might miss them...what got me hooked on them was the fact that
one place had a display tank set up with mature ones.

I agree with Altum that the Rainbows are easier to keep than the African
Cichlids (another option for hardwater). I have a tankful of Mbunas and
they are mean - all from the same lake (Malawi) but still aggressive
towards one another - they look great but breed like rabbits...and the
odd murder is not unheard of...

A couple of newer species tha may be hard to find but are outstandingly
colored are M. parva and G. pseudoinsicus (sp?). Both are full grown
at around 3" so can be kept in a given tank size than their bigger
relatives.

Thanks for the info. I get Practical Fishkeeping by subscription and
have been on their site a few times. I think I will start to search
out fish I'm interested in there. It's great magazine. I've also
found this newsgroup brilliant for advice and although not everyone
always agrees, there is usually a clear consensus. (Thanks everyone!
:) )

I've loved the look of Rams ever since I saw a lovely species tank of
Sunburst Rams at my LFS. I read up about them a while ago and decided
against them in the end because people seemed to have experience of
them dying for no apparent reason. Maybe it is the water thing -
perhaps they are not a fish which adjusts well? Stunning though.

Thanks,

====================
I pretty much do what Gill does. If several sites or books say suchandsuch
a fish comes from soft water and another book (or website) contradicts that,
I will go by the several that agree on water conditions.

An example are Angelfish. This fish is supposed to do best in softer water
under 7. and yet they do very well in my water with a PH of 7.6 to 7.8 and
hard - go figure! Bettas which bred easily for me in NYC's softer acid
water don't breed at all here unless the water is treated. At least that's
been my experience.

Like the old PH shock thing - there are probably more things involved than
just PH and hardness/softness.

April's PFK has an article on fish for hardwater - might be worth
reading, although the suggestions were pretty much the same as you have
had already.

I've had terrible experiences with Rams some lasting hours and the
longest lived over 6 months (my current boy). Perhaps I should start
spelling it R*m just in case - lol. From talking to people at both of
the LFS's I tend to frequent they agree with the fact that these fish
are difficult to keep but can do well once the initial adjustment period
is over. I'm still pretty sure this is down to trying to keep low
pH/soft water fish in a high pH/hard water area - it would be
interesting to know if people with soft water have the same experiences
with them. I think that the advice I got today from the bloke in the LFS
about waiting until they had had them for at least one week is certainly
good advice (they arrived last Tuesday)....then hopefully it should
lessen the chance of them dying on me because of the shock of being in
hardwater with a high pH...I don't know how often you get to your LFS
(as I don't really work I can go frequently) but it is worth trying to
monitor the fish that they do get in...

Gill

My boy is about to undergo a tank upgrade - I must admit I am a little
nervous about moving him but really need the space where his existing
home is...and he should love the space in his new tank...

I've used a 20W 24" tube and have tried warm white, cool white, daylight
and chroma 50. I've used screw in fluorescents and 80W of comnpact
fluporescent. The plants grow darker and shorter leaves with stronger
light and larger with dimmer light as they reach up to it.

As to what sepecies of Crypt they are, uh, yeah, well, ABOUT THAT.

I dunno. They're in the wendtii species-complex and I *think* they're
undulatus. They don't divide like wedntii (clusters of plantlets
at the base) but instead throw long runners.

They're the most prolific aquatic plant I've ever seen. I started
with one several years ago and have thrown away hundreds over the
years. And given away 10X that many.

Nah. Soft water fish will only produce viable eggs in soft water. But they'll
live fine in hard water. In fact, they'll live better in hard water than
soft water.

The current issue iof Practical Fishkeeping has an article about this.

WOW - they sound fantastic. I have some wendtii in my betta tank.
Just had a look - no plantlets at the base, but no plantlets coming up
from runners away from the main plant either. Mind you, they've not
been in that long. I'll have to wait and see. I'd love it if they
were the ones you had.

Just my opinions, but
i) soft water fish do badly in very hard water (too hard on their kidneys).
ii) pound for pound, African mbuna are more aggressive than south or central
American fish.
iii) you could never keep any Monodactylidae in such a small tank - they
outgrow 4' tanks.
iv) keeping fish from the same lake will not help with aggression, and is
just as likely to worsen it.

For such a small tank with hard water, I would look at shellies (small
Tanganyikan cichlids), African Gobies (Eretromodus cynostictus (sp?)), some
of the smaller rainbows (ie: Neon Rainbow), Julies (the smaller ones),
Neritidae snails, and Killies (I'm surprised Richard didn't mention them
;~).

Eh. Not in my experience. I keep killifish that are found in 0DH 4.5 pH terra typica
and I keep them in liquid rock. They won't breed in this stuff, I have to use RO
but they do just fine. Scheel (_Rivulins of the old world_ TFH press, 1968) strongly
urges keeping rainforest soft water fish in hard water to reduce occurance of
Mycobacteria which does poorly in hard water to the point of not being a problem.

I've followed this practice for a couple of decades, as does every killifan
I know.

So you agree with my recommendation that some killis would be appropriate in
hard water ;~).

Which soft water fish do poorly in hard water is a complex topic which is
unlikely to be clearly answered anytime soon The smaller the fish, and the
more its complete life cycle has evolved around soft water, the more prone
it would be expected to be, to have ailments attributable to hard water.
Some botia from the Mekong and some tetras from the Amazon are good
candidates. Discus appear to be quite sensitive to gH as well. A possible
distinction might be drawn between fish which use soft water as a spawning
trigger, and fish which will simply not develop eggs in hard water. Too
complex a topic for me.

They might survive, but exhibit mild long term symptoms of stress (beyond
never spawning), such as different growth rates, age, colour intensity etc.
Killis might not be a representative example as they exist at both extremes,
but are there known differences between killifish kept at one extreme as
opposed to the other?
