Can Nerite Snail Live With Oscar?
No, oscars are large predatory cichlids that eat nerite snails, cracking shells and consuming the soft body inside.
Why
- Oscars are opportunistic predators that eat anything small enough to fit in their mouth or can be crushed.
- Nerite snails grow to 1-2 inches with a hard shell, but an oscar's powerful jaws can crack the shell with ease.
- Oscars have a strong prey drive that triggers when they see slow-moving invertebrates like snails.
- Nerite snails have no means of escape from a 12-inch oscar in a standard tank setup.
- Once an oscar learns that nerite snails are edible, it will actively hunt and consume every snail in the tank.
What could go wrong
The oscar crushes the nerite snail shell and eats the contents, doing this repeatedly until no snails remain in the tank.

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
Oscars do best alone or with other large cichlids. Nerite snails do well in peaceful tanks with bettas, tetras, and corydoras.
