Quick Answer
Nerite snails are small algae grazers that work well in many peaceful freshwater aquariums. They do not reproduce successfully in pure freshwater, which makes them popular for planted tanks.
Care and Setup Notes
- Keep the lid secure because nerites may climb above the waterline.
- Supplement minerals if shells show pitting or erosion.
- Do not add them to brand-new tanks with no biofilm or algae.
