Spider Shrimp

Caridina cf. serratirostris, the Spider Shrimp, is closely related to the Ninja Shrimp and shares its remarkable camouflage ability, displaying a mottled brown, green, and beige cryptic pattern that blends seamlessly with leaf litter, driftwood, and natural substrate. Its unusually long, slender legs — which give it its spider-like common name — further enhance its otherworldly appearance.

Spider Shrimp are secretive, slow-moving invertebrates that spend most of their time motionless or creeping carefully across surfaces, foraging for biofilm and organic particles. Their cryptic nature means they are often difficult to spot even by their keeper, making them a fascinating natural history study in a biotope-style aquarium.

As with Ninja Shrimp, captive breeding is not practical as larvae are planktonic. Spider Shrimp are kept primarily as display specimens and curiosities.

Water: 22–28°C, pH 6.5–7.5, GH 4–10; clean, mildly acidic to neutral water preferred. Tank: minimum 20 L; biotope-style with driftwood, leaf litter, and natural decor for camouflage. Feeding: biofilm and fine organic particles; supplement with shrimp powders and fine wafers. Breeding: not feasible in captivity due to planktonic larval stage. Compatibility: peaceful; avoid large or predatory fish; suitable with small nano fish.
