I wouldn't. My old black shark was started killing tankmates at 14 inches, and by 16 inches he had killed a male dovii, 2 oscar, a red devil, and a very large synodontis. He even killed a 2 foot pleco! They just come in at night and chew holes into the sides of other fish or rip the gills off (what it did to the cichlids). With catfish it ate out the eyes and then went for the soft belly. The only thing it would live with were tiny things like feeder guppies or neons... Ended up putting it in a 40 gallon (I was 13 at the time) with my old BP that had a meanstreak. She killed it in one night.
