The classic nerite snail, which probably everyone knows, is monochrome and black. However, there are many different patterns and also colors in these animals.

A breeding or a reproduction in a normal freshwater aquarium is not possible. Therefore, this snail is especially suitable for aquarium owners who do not want reproduction. However, nerite snails still lay eggs in aquariums, which are often not easy to remove. The larva, which normally develops from an egg, needs brackish or seawater to survive. Thus, breeding is only possible in a seawater aquarium with appropriate salinity.

Keeping nerite snails

Keeping in the aquarium of these animals is undemanding. A 30l tank is already enough to put a nerite snail. Ideal is the attitude with shrimp, because this snail does not attack. However, before you buy and put this animal, there should be enough food. Thus, in new aquariums should wait for enough algae to form, so that the animal does not starve. In addition, there should be a cover over the aquarium, because nerite snails often leave the water. A cover will prevent the animals from not finding their way back and drying out.
