I have a 135 gal tank with a 4” Oscar, and about a 2” Green Terror and Jack Dempsey. I can get a male Festae that about 3.5”. What’s y’alls experience with male Festae aggression? I have seen that they are more assertive and not highly aggressive and I have seen that they are just highly aggressive. I had female a few years ago and she was pretty laid back. I let the lfs talk me into giving her up because she was about 8” and would kill everything. Now I wish I wouldn’t have. Thanks for the input.
