Would a Clown and a Ghost Knife get on in the same tank.
At present i have other Monsters but both these knife fish are around 4 inches at present.
125 imperial Gallon tank at present.
theyd tolerate each other most likely.. space is nice for that size.. set 2 caves on both ends. garanT the bgk will pick one . ck might be more out side and about if lucky. .. theyll both warm up to you in a while. try
