I have a 90 gal moderately planted tank with about 35 Rainbows
(most of them about 3 inches) a few tetra and 2 clown loaches. As
far as filtration I have a Fluval 303 and a Quicksand filter for tanks
up to 125 gal.
I only added 3 fish to my tank before I had problems. On both
occassions I purchased my fish at the same place (I should stop
going there). In the past I have had more fish in my tank without
any problems.
Thanks for your help!
