5 Best Algae Eating Snails For Freshwater Aquariums

Snails are oft regarded as a pest in freshwater tanks but there are some types of snails that make good algae eaters. These are the best algae eating snails for freshwater aquariums:

Nerite Snail

Nerite snails have a zebra-like pattern on their shell and are the most common species of algae-eating snails. The reason behind this is because Nerites eat all types of algae and they can rid a tank of algae quickly.

They grow to about an inch in length and should not be kept with large fish that may eat or attack them.

Apple Snails

Apple snails prefer to chow down on plants so they are not a good fit for a heavily planted tank. However, they will eat algae if there is no other food source around.

Thus, for aquariums with little vegetation, apple snails can help control algae, though it is not their preferred food. Be sure to supplement their diet with other sources of food like cucumbers.
