Question

Answer 1

These fish can live a really long time. I'm not sure but I do know that they can grow 2 feet long I've seen it for myself at a very top dollar pet store and they are filter feeders prefering blood worms and the occasional feeder fish. But determining how big they get i'd say they could live up to 15 years.
