their great fish, but the best way to explain it is there like a dog that can't be trained. Mine is always into something. The Huma is very fun to watch, but causes 90% of the probelms in my tank, and the tank is 300gal.
You can't put them with many other fish other than aggressive due to the amount of stress they cause to other tank mates.
I wouldn't trade mine for anything, to much fun to watch.
