My 20 gal growout has quite the weird combination. It has my 4" Datnoid, a Pictus catfish who is spastic, a juvenile blackghost knife, and my juvenile Bluegill sunfish that was being thrashed by a Butterfly Goodeid in my loach tank. Everyone gets along, but definitely an unusual combo of fish. I have black and orange gravel, a large sword plant, and some driftwood for the ghost to hide in. Also added two moon lights for observation of the ghost knife. I read on an earlier thread that they were blind, but mine hides during the day and is out at night.
