None of the bichirs in the tank are small and the one in question is 8” or so.small polys really need hiding spots I have found I tryed removing them so I would see them more and they stoped eating
A single bichir which was doing this before I removed the hiding places.ok put that may also be making your bichir more skitish
The rather rowdy sun catfish have been forced to be with the bichirs as some of the plecos that were previously in with the bichirs started sucking so I had to move them to their own tank and I didn’t want to risk the catfish getting sucked on as well. This virus had killed every plan I had for a tank upgrade but I still can get a 6’ for the bichirs and catfish to inhabit within a year so I’m believing that the additional space will cause the catfish to calm down a bit hopefully helping with this situation. That is of course if the bichir doesn’t kill itself by doing this before then.Some polys are just flighty. Roudy cats can cause it to panic.
Lots of hiding spots and no hiding spots stops fighting, I chose no hiding spots and it solved the aggression issues in which the bichirs weren’t involved.
