Black Helmet Nerite Snail (Neritina pulligera)
One of the best freshwater snails for cleaning hard algae on aquarium glass, stones, driftwood, and smooth hardscape.
Black Helmet Nerite Snails are powerful algae-eating freshwater snails known for their glossy dark shells, strong grazing ability, and excellent cleanup value in planted and community aquariums. They are especially useful on hard surfaces such as aquarium glass, stones, driftwood, decorations, and aquascaping hardscape.
Unlike many general cleanup animals, Black Helmet Nerite Snails are particularly valuable for slow, steady scraping work. If your pleco ignores certain algae spots on the glass or leaves hard algae behind, this snail can be one of the most practical solutions.

I added a few Black Helmet Nerite Snails to my 55-gallon tank and they’ve been cleaning the glass and driftwood for weeks. The algae spots that my pleco missed are now gone. They don’t seem to harm any of the plants and are active during the day. Very reliable for hard algae.

These snails are effective at removing stubborn algae on stones and glass. I noticed a big difference after two weeks. They’re not aggressive and don’t eat the plants. A good supplement for any aquarium with hard surfaces.
