I currently have a 110 gallon. I have 4 smaller clown loaches, 7 angel fish, 7 red serpae tetras, and a 1.5 inch electric blue jack dempsey. I really like the black ghost knife fish, and have been wanting one for awhile, but am scared it won't be able to survive in my tank. I have a sand substrate, and some drift wood and clay pots. I'll add a clear peace of pvc to add some hiding places, yet still see him. While this work, or will he get attacked, or out competed for food etc?
