Planaria in aquarium

Often together with live and ice cream feed, snails and plants in the aquarium water are worms that have a pink and white color and the triangular front part. They are called planaria and can be dangerous to the health of the shrimp. Often these worms belong to the species Dugesia gonocephala or other varieties of flat worms that live in fresh and marine waters worldwide. Most often they are found in the soil column, but often planarians can be seen on the surface of the water, moving with the help of special cilia on the body. Because of this, they are also often referred to as the ciliary worms.

The planaria eggs are resistant to high and low temperatures, so get rid of them is quite difficult. These worms there is no one specific organ of respiration, the aeration process occurs with just the skin. In order to protect themselves from predators in the wild planaria use of bitter mucus, which is released when receiving a signal of danger. Planaria differ phenomenal survivability. Studies have shown that if you divide the body of the worm 270 parts, each of them is able to regenerate to full body.

They are no less dangerous for adult invertebrates. It is known that planaria can crawl under the shrimp shells, causing suffocation.
