This fish belongs to the shell-catfish family. This fish has a flattened flat body, covered with a shell in the form of horn plates. They protect the fish from stones and snags found in the stream of water.
Armored catfish lack a swimming bladder. In this they differ from other fish.
The length of the ancistrus reaches 14 cm. He has a large rounded mouth with horn suction cups near his elongated lips. On these suction cups there are tubercles (they are called a grater or brush) that help to scrape algae growths from the walls of the aquarium. In this way, they keep the aquarium clean. Therefore, these are the most necessary aquarium fish.
Coloring catfish is diverse. Young individuals have a bluish tint with small white dots. With age, their color changes to light brown, olive, yellow.
Antcistruses are unpretentious. The temperature of the water in the aquarium should be from 20 to 24 degrees. These fish are peaceful, but very voracious. All their lives they have been researching the soil in an aquarium in search of food. Therefore, you need to decorate the aquarium with thickets of plants, stones, grottoes, snags. Catfish will clean them and provide themselves with food.
If you create all the conditions for keeping ancistruses, then you can get offspring from them.
