I need help in understanding why I have lost few fishes. Ihad a pair of clown and they were very happy in my 46 gallon tank which was 2 months old. Then I added 3 chromis pretty big size ones. Just in a few days my clows were dead. After a few more days 2 out of my 3 chromis dead. I don't know why. Some people said that chromis are mean fishes and they hound other peaceful ones. Mine being larger size must have hounded them to death.
After a month of having only one chromis and a couple of shrimp nd handfull of CUC, I bought royal gramma being told they are very hardy fish. But 2 days later she is dead too.
I have checkd my water parameters and they are correct. 0 ammonia, 0 nitrite, <5 nitrates, ph 8.2, water temp 76 F.
So guys help me understand what is going on in my tank? Shall I take the lonely chrmis and return to LFS
and start over with clown?
Do a 50% water change?
Anything else? I am baffled and really saddened with such a loss. I have very happy seeing my clowns running around for food in my tank.
