Dwarf Hairgrass

Care profile for Dwarf Hairgrass: medium-high light, medium CO₂, intermediate difficulty.

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.

Ghost Shrimp

A see-through, feather-light scavenger sold by the handful. Tough across 3-15 dGH and a wide temperature band. Beware mislabeled tankmates: true Ghost Shrimp is Palaemon paludosus, while the larger, more predatory Macrobrachium species are often sold under the same name.

Nerite Snail

The best algae-eating snail for aquariums. Cannot reproduce in freshwater, so populations stay stable. Comes in zebra, tiger, and olive patterns. Will lay white eggs on glass.

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.
