I got myself a pbb Chad around 18" a few months ago. I quarantined it and aa soon as I put it in the tank it started to bite my other bichirs. Not enough to mess them up but to the point where they are pretty much hiding all the time now. I have 8 bichirs right now in a 225g and as soon as they get close to the pbb they get bitten. Will he chill out in time or be an assh*ole forever? Great appetite though and very active.
