I recently added an adult anglefish to my 55 with my other 3 adults. I also have a pictus and pleco in there. Sadly, I woke up today to find a dime sized chunck missing out of my pictus. He has flesh and skin missing, but no organs exposed or gone. He gets scared when I come near, so I cant get a picture. I'm not really sure why this bully fish is picking on everyone else, but I assume it was him because my other adults have grown up with the pictus and have never had a problem with him. I don't know if I should put him, the pictus, down or what I should do with the big bully. Right now he is in the biggest rubbermaid I have (only a gallon) with a lid on top and a thin blanket wrapped around. The blanket seems to keep him calm. PLEASE HELP ASAP!
