yeah, i kept the two that used to cycle my tank (got a couple videos on them in my sig) and they're pretty big now with huge fancy fins. Definitely cool pets as about any other fish.
Elitism bugs me, especially in fish keeping. Whatever fish you keep and think its cool, there are people in the parts of the world where they come from who think westerners are silly for keeping what they eat for dinner as pets.
What do you think about that for a feeder concept?
Heck, I have kept plenty of cool reptiles and used to raise rats and mice for them.. now today I think the rats and mice actually make the better pets. By a far degree actually. They're as smart as dogs, really.
