Can Molly Live With Nerite Snail?
Maybe, with caveats -- nerite snails and mollies share the same water ranges and nerites have hard shells that protect against most fish.
Why
- Nerite snails have a thick coiled shell and a strong operculum that mollies cannot crack.
- Mollies are active swimmers and may knock nerites off vertical surfaces during foraging runs.
- Both species tolerate temperatures from 72-80F and pH from 7.0-8.5, making shared water easy.
- Nerites do not breed in freshwater, so there is no risk of a population boom even if eggs are laid on surfaces.
What could go wrong
Mollies may flip nerite snails while grazing on algae, leaving nerites stranded on their back where they cannot right themselves.
Gear for a shared tank
Sized for the 20 gallon minimum this pairing needs. Affiliate links — we earn a small commission if you buy through them.
AquaClear 30 Power Filter
Oversized filtration is what lets you stock two species together without water quality crashing. Rated for a tank slightly larger than the 20 gallon minimum.
Eheim Jager 150W Thermostat Heater
Holds a steady temperature inside the 72-80°F window both species need.
API Freshwater Master Test Kit
Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
If mollies prove too rough on snails, nerites do well with corydoras or small rasboras.
