Hi, we have Rainbow cichlid fry in a 35l tank.
Very slight level of ammonia, barely reading. Nitrites clear.
Fine and lively until last night. gave them some brine shrimp and put a new rubbery ornament in the tank. Now several dead fry, several near to death and a few that look weak. No idea what has done this. I am gutted, is there anything i can do apart from what I have done which is move them to another tank with absolutely zero ammonia, turn up the air pump a bit and wait?
