Sulawesi Dennerli Shrimp
Common Name: Cardinal Sulawesi, Sulawesi Dennerli
Scientific Name: Caridina dennerli
Wild Origin: Sulawesi, Indonesia
Adult Size: 1 in
The Cardinal Sulawesi is a newly discovered dwarf shrimp that's quickly growing in popularity in the aquarium hobby due to its striking red body covered in tiny white dots. It originates from the Sulawesi lake system in Indonesia, which is characterized by its extremely unique water parameters. This makes Sulawesi shrimp more challenging to keep in the home aquarium. The Cardinal Sulawesi is thought to be extinct in the wild, and is exclusively bred by experienced shrimp farmers and breeders. Its captive-raised status and scarce availability commands a high price.
Sulawesi varieties demand specific water parameters, which make them more challenging to keep when compared to other dwarf shrimp species. Because of this, Cardinal Sulawesi should only be kept by experienced aquarists. All Sulawesi varieties thrive at a higher temperature of 78-85 °F and a pH of 7.8 - 8.2, preferring soft yet alkaline water similar to the lakes where they originate. Ensure the shrimp are kept in a low-flow, well-cycled tank with aged water and plenty of algae to feed on.
Cardinal Sulawesi shrimp are scavengers and will continuously feed on detritus and decaying plant matter in the aquarium. They mainly feed on algae, biofilm, and decaying organics, and their diet can be supplemented with plant-based shrimp pellets/wafers. Adding hardscape to the aquarium encourages the growth of biofilm and algae due to the rock’s rough texture. This provides increased surface area and an extra food source for the shrimp to feed on.

Cardinal Sulawesi shrimp no longer occur naturally in the wild, so breeding lines are entirely captive-bred and maintained by skilled breeders.
Once optimal water conditions are established, breeding Sulawesi shrimp is relatively easy. Starting with larger groups of 10-20 adults offer the best chance of successful spawning. However, Caridina dennerli varieties lay fewer eggs than other dwarf shrimp species. Expect females to only lay about 15 eggs at a time. It takes roughly 20 days for the eggs to hatch and become free-swimming.
