It saddens me to hear the negitive about the humu humu. I have one which I love. He eats out of my fingers, chases our fingers, spits, blows bubbles, watches us, always comes up to the top of the tank to greet us & lets me pet him and yes he nips some times. He seems moody. He is in a small tank right now, but in the next week we will get him a large tank because I love him so much. We want to get him a tank mate, but not sure what to get him. I've read he can co-exist with other triggers and then I've read not to put him in with others, I guess I better buy something atleast his size and cheap. It's nice to have a fish that definately isnt boring! I didnt know a fish could have such a personality! Is there any other fish similar in personality?
