"A most efficient weapon against HAIRY ALGAE in your aquarium. They just LOVE to eat this algae. They will even devour hair algae forms that Siamese Algae Eaters (SAEs) won't touch. Its been noted recently that several forms of Bush Algae will also fall before a FFF onslaught.
This is a tough little fish that lives and prospers under some truly wide water conditions from the very soft, acidic waters of a discus tank, to very hard waters in an African Cichlid tank (though they cannot be kept with those aggressive African Cichlids), to even Brackish water. It is very resistant to disease, temperature changes, pH swings and to water change stress."
