Hello!
I've had a 20g (standard dimensions) cycled and planted tank for a few months now, and I'm noticing aggression directed toward one of my black skirt tetras. I've got eight in all; five white skirts, two black skirts, and one "glow" skirt tetra. But one of my black skirts seems to get picked on extra. This is about the third time I've seen him with rips in his dorsal and/or anal fin(s). He seems to stay in a back corner most of the time, most likely due to the fact that I've got two white skirts that keep him back there. He doesn't get seriously injured, but I'd like to keep fin-nipping to a minimum.
Anyone got any ideas as to what's causing this? Thanks.
