Observation of lepidosirens

Lepidosiren is a strong fish. In nature, it is found in the central part of South America. They live in small rivers, which dry up in the hot summer. In the hot summer they burrow into the mud and wait there for rain. When there is little air in the water, they rise to the top and breathe atmospheric air. Therefore, they have lungs and gills, while other fish do not have this.

They are long, dark gray with yellow dots. Their eyes are like blue beads. Their fins are very similar to thin legs, and they move along the bottom almost like snakes. And in length and color they are similar to eels, but they don’t swim.

Young lepidosirens eat plants and small animals, while adults are predators. Adult fish are caught and eaten.

I watched the lepidosirens every day morning, afternoon and evening, and I also watched how they eat and what they like best. I saw them rise up and breathe. I also watched them bury themselves little in the sand. I watched them crawl and move their houses.

Mom bought two lepidosirens before the New Year in 2006. I was on vacation with my dad, and when I arrived, I saw them. They were small, like teaspoons. Lepidosirens hid in houses all the time and were buried in fine sand and were difficult to see. They could only be seen when they ate or surfaced to breathe. They ate bloodworms and beef heart. They also loved to chew vallisneria and lettuce.

They grew up and their houses were changed. In the summer they stopped burying themselves in the sand and mom removed it.

In the aquarium we have two filters, a water heater, a thermometer, shelters, and soil on the false bottom. The top of the aquarium is covered with a lid with a lamp.

The aquarium was washed when it became dirty. The bottom was cleaned with a siphon, the walls were cleaned with a scraper, the external filters were washed and water was added.

Other fish lived together with lepidosirens: guppies and thoracatum catfish. The lepidosirena guppies ate, and the thoracatums live with them and eat the leftovers. Sometimes we give them snails and the lepidosirens eat them well.

Once upon a time we also had ancistrus, but they severely injured one lepidosiren with their hard outgrowths and their mother took them to work.

Now the lepidosirens have grown: one is 33 centimeters, and the other is 35 centimeters.
