Nerite Snail tank mates

The best freshwater algae snail on the hobby market, with the trade-off that the white egg capsules look untidy and cannot be hatched.

Common mistakeExpecting nerite egg capsules to hatch in freshwater is how keepers invent a fake breeding crisis and scrape panic. Capsules cement to hard surfaces and need brackish water for larvae — they are a cosmetic texture issue, not a population explosion. Accept them, scrape them, or skip nerites.
