Can Nerite Snail Live With Pygmy Corydoras?
Yes, nerite snails and pygmy corydoras coexist peacefully in 10 gallons or larger, with overlapping temperature and pH ranges that suit both species.
Why
- Nerite snails reach 1 inch and spend their time on surfaces, scraping algae.
- Pygmy corydoras grow to 1 inch and hover mid-water in schools.
- Temperature overlap of 72-79F suits both species, with 75F being ideal for corydoras and 76F ideal for nerites.
- The pH overlap of 7-7.4 suits nerites without threatening pygmy corydoras.
- Nerites ignore fish completely and pygmy corydoras pay no attention to snails.
What could go wrong
Nerites may lay white eggs on surfaces in the tank. These eggs do not hatch in freshwater and are cosmetic only.
