The aphanius apodus has the diet of eating small aquatic crustaceans, worms, insect larvae, zooplankton, algae, and occasionally plant material is eaten. If bred for the aquarium, this species can accept dried foods. Although they will eat dried food, it is better for them to be offered small live or frozen food such as ''Artemia'', ''Daphnia'' or bloodworm. There are no recorded threats that could endanger the species into becoming an endangered species. They are known to be found in freshwater.
