Okay, I haven't been able to find anything about this anywhere online... I have 2 Black Moor Goldfish and an Oranda in a 90 Gallon Tank with 2 small Clown Plecos. Today my Goldfish started bullying the Pleco. What's makes it even more odd is that the Goldfish seem to be working as a group. Maybe I'm just too new to this, but that's unusual behavior isn't it? I mean.... correct me if I'm wrong, or if anyone has had anything similar happen. Anything is helpful
