Compatible Invertebrates
4King 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.
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.
Sulawesi Cardinal Shrimp
A stunning red and white striped shrimp from the ancient lakes of Sulawesi, Indonesia. Unlike most Caridina, it thrives in warm, alkaline water (pH 7.5-8.5, 26-30°C).
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.

Elevated ammonia levels cause burns, redness and rapid breathing.
