It would be a long list I think to go over the exact details. I started him on guppies when he was really small, then got him eating bits of cooked shrimp. Always water changes every two weeks. He started in a 20, then 29, 55, and now he's in my 180. For a long time he was eating freeze dried krill and occasional jumbo sticks, now he eats only massivore and chunks of cooked shrimp. Still gets water changes every two weeks.
