Red Wine Shrimp

Caridina logemanni

Also known as Red Wine Caridina

Animalia›Arthropoda›Malacostraca›Decapoda›Atyidae

Red Wine Shrimp are a stunning deep burgundy to wine-red colored variety of Caridina logemanni, prized for their rich, solid coloration that intensifies with proper care and diet. These small freshwater shrimp display the characteristic peaceful grazing behavior of Caridina species and are excellent algae and biofilm consumers. Their striking coloration makes them a popular choice for planted aquascapes and species-specific tanks.

Care

Diet

Red Wine Shrimp are primarily detritivores that graze on biofilm, algae, and decaying plant matter throughout the day. Supplement with high-quality shrimp-specific foods such as Shirakura, Mosura, or similar mineral-rich pellets 2-3 times per week, and offer blanched vegetables like spinach, zucchini, or cucumber occasionally. Ensure adequate calcium and minerals through quality food and water parameters to support molting and coloration.

Behavior

Red Wine Shrimp are active grazers that spend most of their time foraging on surfaces and substrate for biofilm and algae. They are social animals that thrive in groups and exhibit natural colony dynamics, with minimal aggression toward each other. Molting occurs regularly; provide plenty of hiding spots with plants, moss, and hardscape to allow shrimp to molt safely and recover.

Breeding

Red Wine Shrimp require soft, acidic water (pH 5.5-6.5, GH 4-6) to breed successfully, as they are sensitive to water chemistry changes. Females produce small batches of 20-30 shrimplets that develop within the mother's saddle; no planktonic larval stage occurs, making them easier to breed than some species. Provide abundant moss and biofilm to support shrimplet survival and growth.
