Its not wonder the fish fight. Only having 4 feet of territory to squabble against isnt helping. For the same gallonage, you can pick up a 6ftx18"x22".
cookiemonster;1463216; said:Loisellei get about 10 inches. You've had yours for three years? I can't tell exactly from the pictures, but yours look like they're about 6 inches. My loisellei grew from 2 to 7 inches in about seven months.
I don't think you would be overstocked if you returned the oscar to the tank, but the loisellei probably consider the whole tank theirs by now. I wouldn't be surprised if the oscar took a beating upon re-entry to the tank.
Mystix, did you even look at the pictures of the tank? dannyrobot's fish have plenty of room, espicially compared to the fish in your own 35 gallon tank.
