He and the Wide Bar Dat that is about 4 times his size, are getting along quite nicely.
My wife and I were afraid to give him to a friend, when we found out that he has a 15" Albino Channel Cat in a 75 gal. tank.
He got straight up punked as soon as I put him in the big tank, 125 gal., but then he just stared at the Dat like " Why in the world would you want to do that?"
They eat together, they play fun games like "I'll chase you around the tank", and they both swim up to the front of the tank like a couple of puppy dogs waiting for a treat when I walk into the room.
I think they are going to be fine. The FH is too big for the Dat to eat, and the Dat is WAY to big for the FH to kill.
