Ive got a green about 10'' and a walking catfish about 12'' and ive constantly been having to remove the walking cat from my main tank due to him munching on the aros tail.Ive got them in a 8x2x2 with 4 x 6'' pbass,22'' ID shark,20'' GGourami,FRT,Freshwater crab and a couple of cichlids.Do you think it can work? Maybe a few dither fish to distract the walker? I never thought it would be a problem cause the walker is a bottom dweller and the aro a top swimming fish.Any experience with this would be grateful.
