The elf fish, whose scientific name is eared catfish, is native to the southeastern region of Brazil in South America. It is about 4 to 6 centimeters in length. It has a darker brown stripe that goes through the fish's eye and reaches the tail. The parts above the brown stripes are mottled light brown, while the parts below the stripes show a brighter yellow, with brown on the top and yellow on the bottom. With the smart fish eyes, the face of an elf comes to life on the page, so Called "elf fish". Elf fish like to use the suckers on their mouths to lick various moss and algae in the aquarium. Some panmouth catfish will eat aquatic plants, but eared channel catfish will not, so they can be safely raised in large grass tanks.
The elf fish is small and can swim into extremely small spaces. It can eat all the moss and algae, and at the same time, it can also eat the eggs of the most annoying snails such as capsule snails and flat snails in the grass tank, thereby controlling the number of miscellaneous snails. It can definitely be called the best cleaner in the grass tank. Because elf fish mainly feed on algae, when there is a lack of algae in the aquarium, they are easily sick and die. Some individuals will actively eat artificial feed scraps. The suitable temperature is 22-30 degrees Celsius. It likes weakly acidic soft water. It is best to keep it in an aquarium with densely planted aquatic plants and light exposure. This fish has a gentle temperament, does not eat fish and shrimps, and can be kept with most small fish with a gentle temperament. The mouth shape of the Elf is sucker-shaped, so it is more suitable for cleaning patchy and membrane-like algae, and has a good treatment effect on attached algae such as green spot algae and brown algae. But it is somewhat powerless against filamentous algae and hairy algae.
Due to its gentle personality and ability to eat algae, today's elf It can be said that the fish is the most beautiful one on the street of tool fish for grass tanks. Basically, most grass friends have it in their tanks. Therefore, the price of the little fish has also soared. The price on the market is generally black-lined flying fox and small monkey. Three to five times that of a flying fox. In my personal opinion, elf fish are extremely fragile and often get sick or die suddenly. If cost-effectiveness is considered, it is more suitable to be kept in a small tank. In a large tank, one elf is definitely not as efficient as five flying foxes. The above is for reference only. .
