Rudolph (Red Nose) Shrimp (Caridina gracilirostris) – Sleek, bright-nosed dwarf shrimp for planted and low-salinity setups
The Rudolph Shrimp (Caridina gracilirostris) is a striking, transparent-to-pinkish shrimp recognized by its elongated rostrum and vivid red “nose,” which glows under light—hence the nickname “Rudolph.” Active and graceful, they add lively movement to planted aquariums and graze constantly on biofilm and microalgae.
While adults thrive in clean, well-oxygenated freshwater, successful breeding typically involves brackish conditions for the larval stage, making them ideal for display-focused aquascapes or experienced keepers interested in specialized breeding projects.
Moderate
Peaceful, community-safe
Up to 1.5–2 inches (3.5–5 cm)
1–2 years with stable water and excellent filtration
Omnivorous — biofilm, soft algae, powdered shrimp foods, specialized shrimp pellets, blanched greens.
Supplement with mineral-rich foods to support molting and rostrum health.
Minimum 10 gallons (larger preferred for stability and oxygenation)
Temperature: 72–80°F (22–27°C)
pH: 6.2–7.4
GH: 4–8
KH: 1–4
TDS: ~120–220 ppm
(Breeding note: larvae require brackish conditions.)
Best in groups of 10+; highly active mid-water swimmers compared to other dwarf shrimp.
Compatible with small, non-aggressive fish (e.g., micro rasboras), snails, and other peaceful shrimp. Avoid predatory or fin-nipping species.
Provide dense plants, mosses, and wood for grazing surfaces; ensure strong aeration and gentle flow. Maintain pristine water with regular small changes. If attempting breeding, research brackish rearing for larvae.
