The Poso Orange Shrimp is a striking freshwater shrimp from Indonesia known for its vibrant orange coloration and small, delicate frame. These peaceful invertebrates are excellent for planted aquariums and make ideal additions to community tanks with compatible species. They require stable water parameters and a mature tank with abundant biofilm to thrive.

Care

Diet

Poso Orange Shrimp are primarily detritivores that graze on biofilm and algae throughout the day. Supplement their diet with high-quality shrimp pellets, blanched vegetables (zucchini, spinach), and occasional protein sources like dried bloodworms. A mature, well-established tank with plenty of leaf litter and plant matter is essential for their long-term health.

Behavior

These shrimp are active foragers that spend most of their time on the substrate and plant leaves searching for food. They are social creatures and do best in small groups or colonies, displaying minimal aggression toward one another. They will molt regularly as they grow; provide plenty of hiding spots with plants and driftwood to help them feel secure during vulnerable molting periods.

Breeding

Poso Orange Shrimp breed readily in freshwater without requiring brackish conditions, making them excellent for home aquariums. Females produce small batches of 20-30 shrimplets every few weeks under good conditions. The larvae develop directly in freshwater, and juveniles will appear in the tank if predation is minimized and food is abundant.
