Corybits is a food in the form of bits for Corydoras. Conventional crested Corydoras foods were designed to be sized and soluble so that they would not be taken by other fish in a mixed aquarium, but this product is for Corydoras in a single aquarium. It softens quickly, so it can be eaten in one bite, and it does not crumble, so it does not make a mess. It is highly nutritious, so even males, who are said to be less likely to gain weight, will grow plump. "Hikari bacteria" is also expected to suppress the growth of bacteria in the substrate.
