I've heard this same feedback a lot, but my glasscats ARE the aggressive fish in my tank. They will push my Gourami and Angel out of the way at feeding time. I'm pretty sure that mine are an aberration though, so I would go with CG's comments.Calico Goat said:I have seven glass catfish, and the one thing you have to worry about is they are extraordinarily delicate fish. You cannot under any circumstances keep them with anything that migh be remotely aggressive.
