a little over a month and mine has great personality, but wont look at any food i put in the tank that is not moving so i am not sure if you can pellet train them.
lol for your sake I hope it happens sooner then later, do they just lurk, or do they actually move around? (sorry for hijacking your post with my questions)
that sounds neat, I'm just asking questions cause i've been considering getting one, but i'm afraid its just gonna sit there and I want something with personality.
