Onion Nerite Snail (Medium) Aquarium Glaser

Onion Nerite Snail is a lesser-known but visually appealing variety of Vittina or Neritina species, likely named for its rounded, bulbous shell shape and subtle banding or coloration that resembles an onion. While not as widely recognized as Zebra or Tiger Nerites, it shares the same excellent algae-eating abilities and peaceful temperament.
