I've had him 4 months now and he's getting bigger. Also changed the decor of his tank around a bit.
edit:
I just wanted to add, he's a friggen maniac. He jumps out of the water when I open the lid to feed him - one time getting tangled up in the feeding ring I have. Reminded me of the movie Jaws when the shark gets stuck in the shark cage after trying get to Richard Dreyfus. He's ripped the feeding ring off the glass repeatedly and I had to flip it over because he was tearing chunks out of the styrofoam insert. He bit me twice about a month ago when I was cleaning the tank (hasn't done it since thank goodness - now he just follows my hand around - I like to think he was just showing me who's boss). Today I was fixing a filter issue and I was over the tank getting to the overflow and he repeatedly rammed the glass hood. Not taps, but BANGS with the glass hood coming up. His way of telling me "You're up there so FEED ME DAMMIT!".
He's scared to DEATH of the magnet algae cleaner I have in there though. I have to go EXTRA slow with it or I swear he'll come right through the glass.
