Green Long-rostrum Shrimp Care Guide
Caridina longirostris (green form) · Freshwater Invert
What Green Long-rostrum Shrimp look like
The green Long-rostrum Shrimp is a color form of Caridina longirostris with a transparent to translucent olive-green body and fine pepper-like speckling. Adults remain in the small 3-5 cm shrimp range and show the same long slender rostrum, long antennae, delicate walking legs, visible internal organs, and fan-shaped tail as the base form. The green tint often reads as camouflage among moss and plant growth.
Behavior & temperament
This variant is a peaceful benthic grazer that works through moss, driftwood, leaf litter, and substrate for biofilm and fine algae. Keep in groups with calm nano fish or other gentle shrimp, and avoid predators or aggressive feeders. Stable mature freshwater is important; breeding should be considered advanced because larvae may need brackish or marine conditions.
Diet & feeding
These Caridina longirostris color forms graze biofilm, algae, diatoms, detritus, and fine organic material from stones, wood, leaf litter, and plant surfaces. Keep them in a mature aquarium with visible biofilm and supplement with shrimp pellets, algae wafers, blanched vegetables, leaf litter, and occasional powdered foods. Avoid overfeeding because small atyid shrimp are sensitive to fouled water.
Behind the name
Green describes the mossy olive body wash; longirostris means long-beaked or long-rostrumed.
Plan your tank
Check the numbers before you buy: tank volume, a stocking plan, cycle progress, water changes, and your ongoing care routine.
