That fish is huge. I am amazed on how fat its gut is in that video. I would have to feed multiple times a day, everyday, and be there for a while as I add the food to make sure it is stuffed without extra being wasted. I'd leave a nori clip full, but it likes to rip it off and let if float away even when it isn't hungry.
Treny, you could had feed that puppy full each time with its temperment.
