I love your set up I had my Oscar in a tank with sand and other gibberish and that was a bad idea seeing everything turned over or moved the next day I have a 75 gallon tank but the way he’s growing and his tank mate the Pleco I’m definitely going to have to go bigger
Ngl 125 gallon would probably be absolute minimum for plecostomus. But you would be better getting 125+ cos you could have more tank mates Edit: I am sorry to if I across as an arse
Agreed. Take out everything that isn't an Oscar and the tank would be fine. The flower horn, pacu, catfish and the various other fish would be much happier to be housed differently, IMO.
I have 7 and I can’t seem to put one of them with the others he’s bullying all of them. Should I just keep them together and they will relax after a while or keep them separated ?
