Nerita Snails are an efficient scavenger ideal for smaller ponds and freshwater community aquariums. The Nerita Snail is a popular choice for keeping uneaten food and algae in check. It is peaceful and will not unexpectedly overpopulate your aquarium or water garden since the Nerita Snail is difficult to breed (impossible in freshwater!).

The sex of the Nerita Snail can be determined if there are numerous individuals of the same age kept in the same environment and fed the same foods. In which case, females will be larger than males. In order to reproduce, the Nerita Snail requires brackish water as it has a marine larval stage. Adult snails will live about 1 year under the right conditions.

A scavenger, the Nerita Snail will consume debris, uneaten food, and algae in the pond or aquarium. If insufficient food is present, supplement with a quality flake or pellet food.

I own a Nerite for my 5g tank. He is very efficient at cleaning up uneaten flakes. He is also a real trooper, he will not pull in to his shell if you remove him from the water. Once I accidentally dumped him behind my dresser and found him 2 hrs later. I was sure he was dead, but within 5 minutes, he was crawling around. He will even crawl around my hand out of the water if it's wet. Strangely I can't get him to eat algae wafers unless they are soaked and crushed. I named him Gary.

I have a planted aquarium for close to 5yrs. and have not been very welcoming to snails in the past. So when I read that these snails probably wouldn't breed in a freshwater tank, I thought I would give them a try. They started working on the algae build up on the glass immediately! So far they haven't attempted climbing around on my plants. These snails are absolutely beautiful and add a lot of color and interest to my aquarium. I would definitely recommend them anyone that may not want snails populating their aquarium.

I bought 4 of these snails for a planted tank I've been building for about a month now aaaaaand they reproduced. I'm just as shocked as you are. I have baby snails in my tank now.
