Ok, I've decided that I'll put the two rhoms together.
the tank is already setup. put some big@ss driftwoods on the small rhom's side so that Ares hopefully won't break down the egg crate trying to get to the other side.
Funny thing is that Ares seems more "out going" now after I divided the tank. usually it'll either swim to the far side of the tank or stalk me behind a driftwood. now it just swim right to the open to check me out. probably protesting, "why the hell you re-arranged my mansion without my permission? I don't wanna share with an other rhom. I'm gonna eat that bastard one day, you'll see. just watch me".
the 75g is also done for the wolffish, what do you guys think?
