Black Ghosts are really neat fish. Fun to watch at night or during feeding time. Gotta love those tubes, but just go to the hardware store near you 'cause you can make one for less than a dollar .
i have seen a 30 inch clown knife.. let me tell you it was an impressive fish. some peple just dont belive it when you say it will out grow their tank...
OK, I'm worried. I have 2 ghost knife fish at the moment, they're about 3 inches long. What are the problems with other fish? And how big do GKF grow?!?
