Compatible Invertebrates
4Assassin 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.
Cherry Shrimp
The most popular freshwater shrimp — bright red coloration, extremely hardy, and prolific breeder. The gateway species for shrimp keeping. Tolerates a wide range of conditions.
Great Ramshorn Snail
The large, coiled ramshorn that doubles as a cleanup crew and a living water-quality alarm. Every individual is hermaphroditic, so any pair can breed - populations explode only when overfeeding creates a feast, and they shrink right back once feeding is cut back.
Red Cherry Shrimp
A tiny, vivid red dwarf shrimp that breeds easily and endlessly entertains. Fine in nano tanks from 20 L; keep GH 4-15 dGH for successful molting, avoid copper-based medications entirely, and use a sponge filter so young shrimplets never get sucked in.
