It has got to be a Clown. I have a mature one, and it acts like a puppy dog when it sees me. But, be warned, you will to put in its own tank eventualy, as they can destoy every living thing that lives with them for no reason.
I love my huma. Is more like a dog. Well come up to the tank, play fetch with ping pong balls, and can pet it ( all as long as its not hungry!) and not to be rude, but none look better than the picasso.
Clowns Are cool.... but i would say the most personable is the queen. Although it might try to bite your hand off at times they are super active... but u need a huge tank...for most triggers except picassos and udulateds... actually black hawians are active and don't get to big.
