This extra small, long-lived dwarf shrimp has incredible coloration and is relatively easy in care!
The Cardinal Sulawesi Shrimp is an exceptional dwarf shrimp species that is fairly new to the aquarium hobby. Native to the very unique Sulawesi lake system in Indonesia, it was discovered only a few years ago and is now being bred in small numbers by expert shrimp farmers and breeders. It has become increasingly popular to aquarists in a very short period of time due to its incredible coloration, which is an overall bright red or scarlet with numerous small, white spots, as well as white antennae and front appendages.
While it is a completely peaceful and very small dwarf shrimp, the Cardinal Sulawesi Shrimp requires a few different water conditions than most other dwarf shrimp and should only be kept by the experienced, dedicated aquarist. The aquarium should mimic Sulawesi conditions, especially a high temperature of 78° - 88° F and a pH of 7.8 - 8.2, although some breeders have reported success with a pH as low as 7.0. We keep our specimens at a pH of 7.8 - 8.2. Water flow must be very calm and water changes should be kept to a minimum other than the replacement of evaporated water. Both adults and fry require full freshwater.
This shrimp is a scavenger and is very useful in planted and nano aquariums. The bulk of its diet is biofilm, algae, and decaying plant matter so it will work diligently to clean up the waste in any aquarium. It feeds constantly, so it displays constant activity. The Cardinal Sulawesi Shrimp particularly likes to pick biofilm from rockwork and, if present, the shells of Sulawesi snails. This shrimp requires very little or no supplemental feeding in a well-established aquarium.
The Cardinal Sulawesi Shrimp is more challenging to keep than many other dwarf shrimp, but will thrive and breed readily when kept in optimal conditions.

- Diet: Scavenger that feeds continually. Most breeders report that this shrimp should receive no supplemental feeding and therefore must be kept only in a very well-established aquarium with plenty of biofilm. Any supplemental feeding should be very sparing. Our Spirulina flakes and BacterAE make excellent staple food products for these shrimp.
- Warning! Avoid any food product, medication, or plant fertilizer that contains Copper of any form. Copper is toxic to invertebrates. Many commercial fish foods, medications, and plant fertilizers contain copper or more commonly copper sulfate. Always look at the ingredient list for any product going into the aquarium to ensure they are copper free.
