Poso Orange Shrimp
Caridina glaubrechti
📍 Poso Lake, Sulawesi, Indonesia
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 Guide
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.
Tank Mates
Small, peaceful algae eaters that share similar water parameters and do not prey on shrimp
Tiny, non-aggressive fish that occupy mid-water column and do not threaten shrimp
Provides dense plant cover and biofilm growth essential for shrimp grazing
Hardy plant that creates shelter and supports biofilm development without being uprooted by shrimp
Dense moss provides ideal grazing substrate and molting refuge for shrimp colonies
Tiny, peaceful fish that will not predate on adult shrimp but may consume shrimplets
Common Diseases
Molting Complications
Shrimp stuck in old exoskeleton, inability to shed properly, lethargy after molting
Ensure adequate calcium through cuttlebone or mineral supplements; maintain stable water parameters; provide plenty of hiding spots; do not disturb molting shrimp
Copper Toxicity
Lethargy, loss of appetite, discoloration, sudden death in otherwise stable tanks
Perform immediate large water change; remove any copper-containing decorations or medications; use only copper-free treatments; test water for copper contamination
Bacterial Infection / Fungus
White fuzzy growth on body, cloudy appearance, lesions on exoskeleton, reduced activity
Increase water change frequency; improve water quality and oxygenation; remove affected individuals if possible; avoid antibiotics as they harm beneficial bacteria; maintain pristine tank conditions
Parasitic Flukes
Excessive scratching against surfaces, rapid gill movement, visible parasites, weight loss
Perform frequent water changes; raise temperature slightly if tolerated; use copper-free parasite treatments designed for invertebrates; quarantine affected shrimp if possible
