Yep. Only towards other fish. I have a sexual pair, so there really isn't much aggression between them. Now I have one in a "rehab" tank because he has a fin injury and the other is enjoying himself in my outdoor rosy red breeding tub.

I decided I didn't want rosy reds anymore. I want bona fide fatheads. I read an article that said they could be hybrids, and I hate hybrids.
P.S. If anyone has any of the fish on my "Want" list on my previous post, I am willing to trade or pay for shipping(and the fish if you hold the proper license(s) for selling them). Please send me a PM.
