Harlequin Shrimp
Hymenocera picta
Extraordinarily beautiful shrimp with large flat claws and white-and-pink/purple spotted pattern. Specialist predator that only eats starfish β a specific feeding commitment.
Sulawesi Cardinal Shrimp
Caridina dennerli
The Sulawesi Cardinal Shrimp is arguably the most stunning freshwater shrimp β 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 β 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.
Sulawesi Harlequin Shrimp
Caridina spinata
Stunning white shrimp with deep blue or red spots. Endemic to ancient Sulawesi lakes with unique water chemistry. Requires warm, alkaline, hard water β a true specialist shrimp.
