Suitable Plants

Vallisneria spiralis

Weeping Moss

Monte Carlo

Duckweed

The smallest flowering plant — a tiny floating fern that doubles its coverage in days. Excellent nutrient absorber but extremely difficult to remove once established. Use with caution.

Compatible Invertebrates

Vampire Shrimp

A large, impressive freshwater shrimp with fan-like appendages used to filter feed from the current. Can grow up to 15 cm and requires strong water flow and clean, well-oxygenated water.

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.

Amano Shrimp

The classic algae-eating workhorse shrimp, unmatched for clearing hair algae from planted tanks. Hardy at 3-15 dGH, but never breeds in freshwater: its larvae need brackish water, so all reports of 'Amano babies' in freshwater tanks are actually other shrimp species.

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.
