Elf fish mainly feed on algae. When they are cultured in a fish tank, they usually do not need to be fed specially, and they will find algae in the fish tank to eat. Although a few individuals can also eat fed fish food, most individuals can only eat algae in the fish tank. If there is no algae in the fish tank, you can feed some bottom, vegetarian feed, or prepare some algae, put it in the sun, and then put it in the fish tank for them to eat.
The elf fish can eat brown algae, but they don't like it very much. They prefer to eat algae. If there is a real shortage of food in the farming environment, they will also eat brown algae. However, if the introduction of elf fish into the fish tank is to remove brown algae, it is recommended not to introduce elf fish, but to introduce black shell shrimp. They prefer to eat brown algae and can eat the brown algae in the fish tank.
Elf fish is very small, adult body length is about 4-6cm. They are flexible and can swim into water plants, sunken trees or rock crevices to eat troublesome snail eggs. And because they can eat snail eggs very cleanly, many people have introduced elf fish in order to remove snail eggs in fish tanks or aquariums.
