Pistia stratiotes is an aquatic plant first discovered in Africa, but with a wide native range which includes tropical and subtropical areas of the world. It has also been introduced to Alabama, Aruba, Bermuda, Canary Is., Colorado, Hawaii, Illinois, Italy, Japan, Kazakhstan, Netherlands, New Caledonia, New York, Palestine, St.Helena, Turkey, Ukraine.

This is a floating plant, whose several roots reach the bottom in shallow waters. The flowers are usually hidden between the light green leaves forming a rosette covered in short hairs. On the water surface, it propagates, forming large colonies. In point of fact, it is considered an invasive plant, and it grows fast in waters with high nutrient content. However, it is very popular among aquarists and can be easily kept in a biotope aquarium.

Aquarium equipment

The tank should not have a strong current, as the plant can be moved or submerged by the flowing water. Pistia stratiotes is compatible with most fish, although larger ones, like cichlids, may damage it. It should not be paired with goldfish or any other large herbivore fish, as they tend to eat the plant .

Plant care

Pistia stratiotes is easy to care for. It requires removal of excess plants and yellow leaves and good access to nutrients. This plant does not do well in bright light, so, that should be introduced slowly and progressively.

Water care

In the biotope aquarium, water should be slow moving or with no current at all. The water should have a neutral pH and the temperature is to be maintaned between 21 and 27°C
