Someone explain reason behind this

I have always been told never to feed freshwater fish..sal****er
foods, and never to feed sal****er fish freshwater foods...be it
frozen or prepared items. Was always told its to keep from
introducing foreign critters into the environemnt that the fish are
not used to.

So whats the difference when it comes to feeding brine shrimp or
krill or any other number of frozen foods that say Fresh or salt water
fish on them. I often acclimate mollys or guppies to SW and feed
varous SW fish live foods. Last I read sw micro organisms do not
survive in FW anbd visa versa, so I am having a hard time reasoning
with the no to feed sw to fw etc etc.

I have fed what I wanted to feed all the time and as long as the fish
etc eat what I give them thats fine.......and have never had problems.
So whats everyone else's take on this? I have a bunch of cichlids that
will tear up my home brew frozen SW ifsh food which is mainly chopped
and diced and pureeded shrimp, krill, mysid, scallops, clams and
muscles and squid and assorted what ever is cheapest at the time some
kind of SW fish.

Actually I always heard it the other way round - feed SW to FW and FW to
SW....because the pathogens for SW cannot survive in FW and vice versa...

See above....looks like we have heard the same thing....

Your way of thinking is also how I view it. Seems some online web
based forums do not view it that way....After all thats the reasoning
used behind hyposalinity with SW fish to rid a fish of parasites etc,
introduce it to FW so organisms are killed off........Add salt to FW
so those organisms are killed off..on FW fish etc.....All I know is I
have never had problems with what I feed to who so I guess there is
no need to change or modify it.

We never had a problem on the other aquarium groups until you came along and
trashed our groups. Why is that Tristan? Why trash several other groups and
not this one? What's different about this group? Why do you feel the other
groups don't deserve peace but this one does? Tell us why you troll the
other groups and not this one.

Roy "Tristan" Hauer NET-STALKER SUGGESTS MURDER of cripples and old ladies
spewed more vomit in message
...
Some just need to be knocked in the head and tell God they died........

You gonna knock her in the head hero? Gonna use a crowbar or a brick? You
need to get back on your meds. Get
back to the VA where you belong before you kill yourself of someone else
when you finally flip your cookies.


Its quite evident a raw nerve was struck on CArol Gulley once again as
the truths of this person comes to light. When this happens you always
get a full melt down, in her quest to try and cover up and detract
anything that was in direct truth with her and her ways.....Get over
it carol we all lknow who is behind this mess. You can point your
finger all you want, we jusyt look at the arm its attacked to and then
look up and its your mugg, no matter what name is used.....

Your a real pathetic individual carol........not one other group
thinks for a minute allthose psts from Bellsouth is from me. They know
its you or at least you are responsible for it.......your loosing it
Carol.....Please turn on that camera so we can witness this real time
meltdown........and your welcome to webcam your nudie shots to
your favorite vermin and rodent extermination groups with it after
we get to see your meltdown......

From the point of view of pathogens, freshwater foods are probably
more safe to sal****er fish and vice versa... quite obvious.

The problem with feeding foods from different environment is
in my opinion related more to nutrition composition - feeding
freshwater animals to marine predators would probably cause
malnutrition since freshwater foods did not grow eating marine
plankton but rather terrestial plants, insects, fruits - different
food chain. Marine fish should eat marine foods rich in fatty
acids and nutrients found in the sea not terrestial plants, right?

Absolutely so here is the dilemma....on one hand it is good to feed FW
stuff from SW and SW good from FW from a pathogen and disease prevention
point of view...but on the other hand the nutritional requirements
differ....so if you feed FW fish exclusively on stuff from SW then you
are storing up health problems with liver/kidney/mineral
deficiency...and if you feed SW exclusively a freshwater diet you are
depriving them of the high protein diet and the type of plant matter
they can naturally digest....

Now logic would actually suggest that FW eat FW stuff and SW eat SW
stuff....but there are a number of articles that suggest that this is
the wrong way to go in terms of controlling disease and pathogens....but
nutritionally it doesn't make sense....

So by following this doctorate are we actually shortening the lives of
our fish and critters by protecting them from disease in the short term
only to get long term health issues? Or should we actually be
concentrating on finding healthy foodstuffs free of pathogens for both
our freshwater and sal****er buddies?

Gill

Dunno, but I have a hard time beliveing that food stuff harvested from
FW or SW is really handled so that it is not a cesspool of pathogens
fron setting in the sun, becoming warm etc etc., Afterall its a fish
etc that is eating it, and who could tell one way or another if lousy
substance was indeed the problem, or how it was handled or how it was
stored and handled by vendor.......there is a long list of "what ifs"
in regards to decent food.....Heck we all know food destined for human
consumption is also not handled properly.........nor is feed stuff
intended for cows and other domestic critters made and stored
properly....
My wife is always condeming trailer loads of foods destined for
grocery stores all due to handling issues........so we can allpretty
well assure outselves pet foods are probably a deplorable
substance....then again animals can usually tolerate foods that a
human being could not dream of eating.........so maybe short of
nutrion its all not worth while being concerned with if your buying
spoiled frozen or stuff thats worth the price they ask.

I guess I will go on with making and feeding my home brew SW foods,
and also feed it to those FW fish that will eat it.....supplement what
I make with decent brand name at least pelleted feeds on both ends FW
and SW.

I see you don't trash this group with personal attacks on other posters. Why
is that Roy Tristan? What makes this group and it's members immune from your
attacks and trolling? You realize you've destroyed the pond, goldfish and
misc aquarium groups don't you? What's your motive Roy Tristan, for
destroying all those other groups. You even invaded the rose group to get to
your victim Gail. If we all move here will you let us post in peace and stop
calling the women sluts and whores and telling the disabled to commit
suicide as you did Ed Alston?

There is no dilema!
Deep frozen stuff you buy for your fish
is pathogen free and safe to feed to your pets...
Unless you feed live foods you should be perfectly fine.
The best food for marine animals is marine in origin.
