Just the other day i was talking with my brother about the hobby we love so much. And we both said, This truely is a fish that don't belong in a fish tank. The speed and power are second to none. I have another growing out. So i'm not trying to preach to ya'll. But if you keep them past 10-12'' You'r just taking a huge risk. There speed/power are ever far worse than even Armatus. I think it's because of the strong current in the river's over there? But when large they are a joy to watch roam your tank. When past 12'' they start to understand what they are.. Top of the damn food chain. It was a true honor to keep this fish.
