I have the Tetra Crisps that were the 3 different types in one (green, red, orange). I REALLY liked the Crisps a lot better as it was harder to overfeed with them. They recommend 1 crisp per inch of fish. The only downfall (if you have smaller fish) is that sometimes they are harder for them to eat and they have to pick at them instead. (happened with my neons).
I usually feed the crisps, frozen bloodworms, frozen
brine shrimp, and veggies to my fish on a rotation, so anything the crisps may lack is made up with the other foods.
