Vampire Crab

Rabbit Snail

A large, striking freshwater snail with a conical shell and colorful body. Comes in orange, yellow, and dark variants. Active algae and detritus consumer, but slow breeder.

Zebra Nerite Snail

A striped, hard-working algae grazer that never overpopulates: its eggs are laid all over the glass but only hatch in brackish water, so they simply stay put. Prefers harder water (GH 6-20 dGH) with calcium for a healthy shell; watch for escapes, as it can climb out of open tanks.

Assassin Snail

The striped predator of the aquarium world, kept to hunt down pest snails and worms. It burrows by day and hunts by night, and will happily share a tank with fish and plants - it ignores shrimp and fish entirely. Also known as Clea helena; both names are accepted.
