Cardinal Sulawesi Shrimp

The Cardinal Sulawesi Shrimp (Caridina dennerli) is a freshwater aquascaping invertebrate appreciated for intense red coloration with bright white spotting and white foreleg markings. When maintained in stable water and mature planted systems, this species contributes both visual detail and practical ecosystem function.

Appearance and Aquascaping Role

Cardinal Sulawesi Shrimp is widely used in planted layouts because it adds natural movement without disturbing hardscape composition. Its presence helps make an aquarium look biologically active while supporting day-to-day maintenance tasks.

Size and Lifespan

• Adult size: about 2.5 cm (1 inch)
• Typical lifespan: 1.5-2.5 years with consistent husbandry

Ideal Aquarium Setup

• Recommended tank size: 15-20 gallons (55-75 L)
• Temperature: 27-30 C (81-86 F)
• pH range: 7.8-8.4
• Water type: Freshwater, stable and well-established

Provide textured surfaces (wood, rock, moss, mature plant leaves) so biofilm develops naturally and grazing behavior stays consistent.

Behavior and Compatibility

Cardinal Sulawesi Shrimp is active but highly sensitive to instability, especially in new or immature tanks. Compatible tank mates include species-only Sulawesi communities or very carefully chosen warm-water peaceful companions. Avoid housing with known invertebrate predators or aggressive species that may pick at antennae, legs, or shell openings.

Diet and Feeding

Feed a varied program based on biofilm, algae films, specialized Sulawesi shrimp foods, and controlled micro feeding. In planted aquariums, natural grazing should be treated as supplemental nutrition rather than the only food source. A rotating feeding schedule improves resilience, activity, and long-term coloration.

Breeding and Population Notes

can breed in freshwater, but long-term success depends on tightly stable warm alkaline parameters. For best survival and predictable numbers, keep maintenance regular and avoid abrupt shifts in temperature, pH, or mineral balance.

Why Use Cardinal Sulawesi Shrimp in Aquascaping?

few freshwater shrimp rival its color impact in dedicated high-end invertebrate aquascapes. For planted community systems, it is a high-value addition that improves both aesthetics and ecological stability when stocked responsibly.
