Compatible Invertebrates
4Nerite 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.
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.
Blue Bolt Shrimp
A striking blue color morph of Caridina cantonensis. Deep blue body with white banding. Extremely sensitive to water parameters — requires very soft, acidic water.
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.
