Very kool, however unfortunately I do not think I am going to get to see him/her grow that large. I think he has broken his jaw from running into the side of the tank. It looks offset to the left.He stalks the fat heads as he normally would. However when he attempted to feed, he cannot open his mouth enough to grab them and they get away. He now just stalks them gets close as if it lunge and turns away and opens his mouth as wide as possible as if to realign it. Bummed out hoping to rectified itself.
