Description
Red onion snails are nerite snails that hail from the freshwater lagoons, streams and mangrove swamps of Indonesia. Growing up to 2.5cm in length, these popular algae eaters are best identified by their eye-catching red and amber shells dotted with black.
Red onion snails can be kept individually or in groups. Be mindful that they depend on sufficient algae within the tank, so you may need to add cucumber and algae wafers to supplement their diet.
Red onion snails prefer moderately hard, alkaline water, as acidic water will dissolve their shells. They cannot breed in freshwater, as their young need brackish to marine water to develop. Healthy plants are left alone.
Red onion snails are excellent escape artists so be sure to secure the lid on their aquarium at all times!

If livestock are appearing out of stock on our website, it does not necessarily mean that they are not available in store. If there is something that you are looking for, please contact us and we will be happy to discuss what is possible.
