First time poster, long time reader.
I was hoping you guys could help me out solving this mystery. Two days ago I purchased a couple Large Pictus Catfish (5" Long) from my LFS
. They were doing well an appeared happy, no unusual behaviour. One day later I came home in the afternoon and fed my fish, then about two hours later I came back and found both catfish dead. No bite marks, no disease visible, just dead. I was shocked because they looked perfectly fine at feeding time.
Info on my tank:
<5 ppm NO3
Tank has been set up for over 2 years
Bellow substrate and a canister filter
2 Oscars 4"-5"
2 Rainbow shark 3"
Other fish are doing fine.
Look forward to the replies and thanks in advance.
