Sulawesi Cardinal Shrimp
Caridina dennerli
Family: Atyidae
The Sulawesi Cardinal Shrimp is arguably the most stunning freshwater shrimp — a brilliant red body adorned with white spots, from the ancient alkaline lakes of Sulawesi, Indonesia. It is also the most demanding, requiring very warm water, elevated pH, and unique mineral composition mimicking its ancient lake habitat — parameters almost opposite to other Caridina species. It is intolerant of standard aquasoil buffering and must be housed in species-specific setups using Sulawesi mineral salts.
