I make up my own flakes now. I buy tropical flakes Nutrafin, I mix in bloodworms, Brineshrimps, tetramin algae crisps. My 55 gal. community fish tank fish love it. I have 1 lg. angelfish, 6 harleqen rasboras, 6 dwarf rasboras, 2 bushynosed plecos, 4 assassin snails, 3 bubble bee platies, 2 boesmani rainbow fish. You can make up a mix for your tetras. If the flakes are to big crush them a little. I put all this in a big zip lock bag and put some in a plastic food container that the food came in. This is good if you have a community tank with different fish types.
