i've heard that flower horns are very aggressive but other seem to be able to live with fish so is it just certain types of flower horns that are aggressive for example are ZZs more aggressive then KAMFAs ?
My female is weird she gets along great with some and hates others, in the end I think it all comes down to each fish's individual personality and the mood they are in at the time, after a good feeding she could care less who is there but if she's hungry or getting ready to lay eggs all bets are off.
My male ignores all his tankmates until they get around his territory at the top/front of the tank (feeding position). He just sits there and does somersaults all day until the food hits the water. He's an insatiable little beast!
