Before it goes in
- Nerite Snail needs at least 10 L (3 gal). The smallest size in this library that clears that is the 45F Shallow.
- It leaves shrimp and small fish alone.
- It holds at 68–82°F (20–28°C). That shares a window with Betta and Cherry Shrimp.
- It jumps. An open-top tank needs a lid or a low water line.
- It grazes algae hard, which is most of the reason people buy it.
- Sources say not to put it in a newly set-up tank — give the tank a few months first.
