Hi ppl's,die
Around two weeks ago I added 10 fish (6 comets & 4 small catfish) to a new aquarium that had been cured for around six weeks.
Last Saturday, the water started clouding, so I did around a 30% water
change (this is a 60 litre tank). Almost immediately the Comets startedto
with the last one going off this morning.on
Curious thing is, the catties are totally unaffected.
I use a very coarse gravel over a UG filter as well as an external "hang
the side" filter. All water tests are fine, PH is fine, nitrates &nitrites are
non existant, so the bio filters seem not to be the problem. Thecloudiness
has also gone as of yesterday.an
The water I use is rain water (we are on tanks here) & this has not been
issue with the other tank (I'm in Tasmania, Australia - so acid raindoesn't
even figure into the equation).& the
Just can't fathom why the Comets have died (they are usually very robust)
more "fragile" catties have survived ok.
Any thoughts ?
cheers,
Lance

6 comets, as in goldfish??. One comet, max two in your size tank is all that
should be kept. I would suspect that an ammonia spike killed the fish. Not likely that whatever filter you have on that size tank can have a bio load capable enough of handling 6 comets. Messy fish that create large amounts of
waste which = ammonia spikes. Strange that the catfish didn't go also.

Yeah, 6 - but they were only small & I've not had a problem keeping
that amount in this tank before - my first thought was ammonia too &
the "autopsies" tend to support it, degraded fins in a very short time (but no red gi), mad dashing about the tank & trying to bury
themselves in the substrate - but rather odd that the catties are
totally unaffected (they're all still doing quite nicely). At this
stage, I'm not game to put anything else in the tank yet!
Get an Ammonia test kit. They're cheap and can answer
that question easily.
