I wanted to take the time to thank everyone for your help, ideas and
thoughts. Again, I've had my 55gal going for some time now so I'm what
you would call a newbie w/ the new technology that's out. Thank you
NetMax for your advice awesome webpage. So far I've spent quite a few
hours reading and learning.

I ended up w/ the following:

one magnum 350 pro (it came w/ the 220gal tank)
two AC110s
one 72"x18" Undergravel filter w/ 4 tubes and 4 sponged powerheads

I might endup cutting back on the number of fish that I plan on
stocking. I've always wanted red tailed tinfoil barbs, but due to the
size I just might omit them. The bala shark is one of my most liked
fish, so I will go w/ them for the dither needs of this tank.

I'm also wondering just how big my clown knife is going to get. I see in
the wild they get up to 40"!! goodness! he might eat my Oscar :) i hope
he remembers that my oscar let him live when he was just 3". He's about
6" now.

My current tank is 55g. I got it back in the early 90s. It's been a
great tank thats served me and my freshwater fish well over the years.

I recently purchased an upgrade for $550. it's a used 220gal tank (7'
long 2' thick). it came with a magnum 350 with the 2 bio wheels, 5
powerheads to keep the water moving, rocks, decorations, heaters, stand
and canopy. really, it has everything need to get it up and running.
But, I have a question or two concerning filtration.

I know the amount of filtration you need depends on the amount of fish
you plan on housing in the tank. but I would rather over filtrate than
under :) this is what I was thinking of doing, please let me know your
thoughts:


Primary filtration:

2 magnum 350's w/ bio wheels. (this will give the tank a total of 4 bio
wheels)

Secondary filtration:

1 72"x18" Undergravel filter w/ 4 tubes and 4 powerheads.

Planed fish:

1) 1 large oscar
2) 1 large clown knife
3) 2 large tinfoil barbs
4) 2 large bala sharks
5) 1 large sucker mouth cat
6) 4 med clown loach
7) 1 med firemouth

Thank you for your thoughts on my planned setup and fish. BTW, currently
I own the Oscar, clown knife, sucker and firemouth.

I'm glad you're enjoying the website *and* that you are thinking of
scaling back your fish load. You might want to run the tank for a while
to become accustomed to it. Tanks from 60g to 180g are a change of
scale, but I find that above 180g, previously easy or relatively easy
tasks become a bit of a challenge. Simple things like not being able
to reach the bottom (to clean algae, reconnect pipes and heaters, or to
correct the Oscar's daily redecoration attempts) become mechanical
challenges. Also floor reinforcement, medicating and temporary fish
accommodations during repairs is somewhat 'interesting'.

The down side of adding fish later is that they will always need to be
bigger than your Oscar's 'eyes' (and Oscars see objects smaller than they
really are ;~). I find that you need to have relatively large containers
or tanks (50-90g) to stage fish up to a 220g with large carnivores (I've
used pond liners for this purpose).

Returning to fish load, fish grow bigger and faster in larger tanks, so
expect that some of them *will* reach their adult size, and they will
need a lot of swimming room. The Red fin Tinfoils are a good choice
(imo) as they seem to co-habitate well with Oscars (active but not
overly), and you can get away with some plants (Anubius, Hornwort etc).

As far as I know, both Balas and Tinfoils can reach 16" in length, so you
can expect at least 12-13" in your tank (depends on diet, genetics etc).
Compared to Tinfoils, Balas are a more active, slimmer, faster and more
prone to jumping out. If going with Tinfoils, I would get 4 or 5 to keep
3. With Balas, I would get 6 to keep 4. I've read that Clown Knives top
out around 18" in captivity, so your Oscar is relatively safe.

ps: If anyone offers you a Pacu because you have a large tank, you might
want to decline their offer. I've had one outgrow a 500g tank (too
short) and then an 800g pond (too shallow). There is actually a
significant difference between a 16" fish and a 22 to 24" fish. Every
inch is several pounds (Pacus get over 50 lbs!). In theory you could
raise them for a BBQ dinner (if they have never been medicated in their
10 year life), but I could never do it. They do cook wild Oscars in
Brazil.
