Physa marmorata

Very small snail with brown shell (brown shades can vary from one snail to another). Breathing is done by lungs. They are usually very discreet in the aquarium. When they become invasive, the first solution is to reduce the amount of food given to fish. If this does not work, put a boiled lettuce sheet at the bottom of the aquarium for a few hours and remove it when the snails have stuck there. These snails feed on algae, remaining food and decay plants. They do not attack healthy plants.

The Physa Marmorata snail is a gastropod mollusc belonging to the physiidae family.

Physes seem to be able to reproduce by Parthenogenesis, which in fact in the eyes of some a particularly invasive snail. The eggs are deposited anywhere on the decor (plants, windows, rocks, ...). They are contained in a gelatinous mass. The population regulates itself in relation to the amount of food available. They need a not too agitated corner, and especially with very few fish, since babies are born in eggs.
