Onion Nerite Snails | 3 Pack The onion nerite snail, also called the red onion nerite snail, has a round shell with brown and cream bands with black spots that could resemble onion rings. These nerite snails love to graze on algae in both freshwater and slightly salty tanks. They stay fairly small and won’t reproduce in a regular aquarium. Onion snails are steady cleaners and with unique shell pattern that make them a popular pick for planted and nano aquarium setups. Background and Key Benefits Nerite snails or Neritina sp. are freshwater snails related to the mollusk family. They will clean algae from glass, substrate, and décor. They are also so popular in our hobby because they do not reproduce in freshwater. In the wild these snails return to brackish water to breed and the baby snails require brackish water for early stages of growth. Therefore, Nerite snails will not overpopulate in an aquarium. Along with serving practical purposes in the aquarium, the snails have beautiful shells and they are fun to watch. If you look at your glass closely after adding them, you will see the tiny track marks these snails make as they graze on algae! We keep these snails on pool filtered sand and in bare bottom tanks with a Matten filters. We also use LED lighting to provide enough natural algae growth for them to feed. Please note: During shipping, snails sometimes go into a hibernation-like state and may not become fully active for up to a week once acclimated to your aquarium. Tank Parameters pH: 7.2 to 8.5 GH: 7 to 15 KH: 2 to 8 TDS: 120 to 400 Temp: 68 to 78
