Compatible Invertebrates

Mystery Snail

A colorful, active apple snail that cruises the glass for algae and leftover food. Pairs lay their pink egg clutches above the waterline - remove them to avoid overpopulation. Keep hardness at 7-18 dGH and offer calcium-rich foods so the shell stays strong.

King Kong Shrimp

A solid black color morph of Caridina cantonensis with minimal white markings. One of the rarest and most expensive shrimp variants. Requires expert-level water parameters.

Bamboo Shrimp

Also called the wood shrimp, it stations itself in the current and fans microscopic food from the water with its four feathery feeding fans. Needs brisk flow (8-10x tank volume per hour) and regular feedings of powdered or micro food, or it will slowly starve in a clean tank.

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.
