i read a thread a while back where a guy said he used ping pong balls to stem aggression, so yesterday i went and bought some ping pong balls, even though to tell you the truth i have no aggression problems with my affys, i just figured it would be cool if they went for it. And well they didnt, in fact they hated it, so much so they wouldnt even go near the top of the tank. so i took it out. Just wondering if it worked for anybody else.
