So lets see. It is cool, is known to eat inverts, but MIGHT stay away from ones already in the tank. They usually eat, but this guy says his didnt. They need a good deal of swimming room and do well in captivity, but they may need more cuz bigger is better. Well, I know that. I know I can house it, but I dont know if it will eat my inverts or not. I guess tha the answer to the riddle is pot luck, same with other ?? fish. You have to see how they do. Not all fish are the same. Obviously, these guys are built to take down shelled fish, hence the tusks, but wen it comes to the aquarium, you wont know until you try it out. Thats all we can say on this fish, and i myself, am satisfied. Thanx for the info magic.
