i had 4 pbass in a 125g - also had a wolfish and clown knife --- all fish are in teh 5 -8" range. in the last week the wolf, knife and 2 pbass have died (all on separate nights) i found them when i woke up in the morning - water params /temp are fine.. all fish were eating no problem. the largest pbass has bee the most aggressive in the tank toward all fish, with the exception of the only other fish left in the tank - another pbass- could this be due to pairing off? do they do that at this size ~8"? any help would be appreciated -- i think they are monos or a hybrid mono
