Nerite snails

This little fella takes the top spot on our list of popular algae eater snails. With their zebra shell and their huge appetite for algae, it’s no surprise as to why they are so popular. Nerite snails don’t have a specific preference of what algae they like to eat, as long as the algae are fresh water it will suit them just fine; they even take care of the algae that are harder to eradicate like Green spot algae and green beard algae. These snails are bottom dwellers so they will help clean your substrate.

They grow up to 3 centimeters, but they are very easy targets for fishes like Cichlids and Loaches, so it’s advised not to pair these fishes and snails together. For Nerite to grow and survive for a long term they require water that has a pH level of 7 or above, and hard water is usually preferred because the calcium in hard water keeps their shells healthy.

The only problem with these snails is that they breed like crazy, so unless you plan on breeding them you are better off with just one snail, other than that they make for great algae eaters.
