"I had Serpae Tetras years ago. They were BAD to nip fins and chase other fish. I had a school of 10 in a 55g tank, and they harangued other fish so badly that I ended up getting rid of them.\n \n\n\n\tThe only other type of tetras I've ever owned are Black Skirts. Those were really nice. They didn't school very tightly, tended to be all over the tank (29g), but they never bothered anyone.\n \n\n\n\tI'm thinking about trying Congo Tetras when I can set up a bigger tank after we're in our own place again.\n "
