TetraColor makes a food that specifically says on the bottle that they're big flakes. It comes in a large bottle though.

Too bad it can only be fish flakes because if you wanted to teach your friend a lesson why not to gamble (especially with you) id make him eat freeze dried Krill. Its fish food, comes in a canister, and you can find it at any pet store, its kinda expensive but to see him choke down a handful of those would be well worth it LOL!!!
