The last 2 days my black arowana has been coming down to bottom and mid level water during the night. I usually dump 1 or 2 massivore pellets for my ornate to eat over the night and not more than 30 minutes ago, I caught my black arowana chowing on one of the pellets. It had the pellet in it's mouth for a good while since it couldn't swallow. Once it got soft enough it gulped it down. So I threw another one for the ornate only for it to be eaten again by the arowana. The stomach on the arowana is bulging and it worries me. I had to literally put the pellet in front of the ornate so that the arowana can't grab it. It can't be that the arowana is still hungry...since it gets almost 8 pieces of food sticks all to itself. Can the arowana eat itself to death?
