aggressive black skirt tetra?
so i migrated to college and took my oddly-stocked tank with me. the fish are doing pretty well, with the exception of one.
here's the setup:
10 gallon, 3 black skirt tetras, 2 albino skirt tetras [white skirt]
i added one of them a few days before i went to college. he has turned out to be an extremely aggressive black skirt tetra. this puzzles me, as i've never had aggression issues with black skirts before [i had an aggressive serpae that i returned to the store] he terrorizes all of the fish, so they are constantly in hiding. i bought a new black skirt that's about the same size, slightly smaller. and he hangs around her, nipping her fins, and generally bullying her. i understand that i don't have enough skirt tetras to create a school, [yet!!!] but wouldn't they all be aggressive?
question: should i return the aggressive one and get another black skirt? or is it the situation and not the fish?
when i returned the aggressive serpae, my fish tended to leave each other alone, and they all had fantastic, unchewed fins. now that i have this fish, he nips and rips at their fins all day. they aren't ripped off, but they're ragged.
maybe this fish is just a jerk.
