I was just wondering if anyone else here has these Penguin Tetras, and if you noticed if they are agressive to themselves. I bought a bunch for my 29G, and they seem fine for a while, then they all gather to one area, and then 2 will start fighting while the rest watch. Then occasionally, one of the fighters will move away and another one will continue the fight. It is really strange to watch, something I've never seen a fish do, lol. It's almost like some kind of a competition, lol. And it's not mild fighting either, it's down right nasty fighting, lol.
