Just figured I would put my 2 cents in...considering that used to be my jar:
He's actually very mellow...never had any aggression problems with tankmates other than tinfoil barbs. He was in with a silver and black aro, some dats, a gar, an Pbass and he has been fine.
I just kept him nice and fat and happy and all was well.
He looks good Sticky...I hope all is well.
