Salvinia Auriculata is a cosmopolitan floating fern from 1 to 3 cm high. It grows quickly if it has nutrients and light in sufficient quantity. If its leaves become pale, it is a sign of a micronutrient deficiency. It can prevent low plants from the aquarium from receiving light. Like all the Salviniacae, its pubescent leaves are water -repellent.

It can be used to fight algae because it forms screen in light and it draws the nutrients contained in the water. It can become very large if it has optimal growth conditions. Decorative plant for open bins.
