Snow White Shrimp
Caridina logemanni
📍 Taiwan / Germany selective breeding
Snow White Shrimp are a selectively bred variety of Caridina logemanni prized for their striking pure white coloration with minimal pattern variation. These small, peaceful shrimp display an opaque white body that makes them highly visible in planted tanks, contrasting beautifully with dark substrates and green vegetation. Their pristine appearance and ease of care relative to other Caridina varieties make them popular among both beginners and experienced aquarists.
Care Guide
Diet
Snow White Shrimp are detritivores that thrive on biofilm, algae, and decaying plant matter naturally present in established tanks. Supplement with high-quality shrimp foods such as Shirakura or Mosura pellets 2-3 times weekly, and offer blanched vegetables like zucchini, spinach, or cucumber occasionally. Ensure adequate mineral content through specialized shrimp supplements to support molting and shell development.
Behavior
Snow White Shrimp are active grazers that spend most of their time foraging on substrate and plants for biofilm and algae. They are social animals that do best in groups and exhibit natural molting cycles every 4-6 weeks; provide plenty of hiding spots with moss and plants to support this vulnerable period. Colony dynamics are generally peaceful, though males may compete mildly for females during breeding season.
Breeding
Snow White Shrimp require soft, acidic water (pH 5.5-6.5, GH 4-6) to breed successfully and are considered moderately difficult to breed compared to Neocaridina. Females produce small berries (20-30 shrimplets per brood) that develop over 3-4 weeks before releasing fully-formed miniature shrimp. Provide dense vegetation and stable water parameters to maximize survival rates of offspring.
Tank Mates
Small, peaceful algae eater that shares similar water parameters and does not prey on shrimp
Tiny, non-aggressive fish that thrive in soft acidic water; may occasionally nip at shrimp but generally compatible
Micro-sized peaceful fish that prefer similar soft water conditions and do not threaten shrimp
Larger shrimp species that coexist peacefully; may compete for food but rarely aggressive
Essential plant providing biofilm, grazing surfaces, and shelter for shrimp colonies
Hardy plant that provides grazing surfaces and hiding spots without being consumed by shrimp
Common Diseases
Molting Failure / Incomplete Molt
Shrimp unable to fully shed exoskeleton; stuck in molt, lethargy, death if not resolved within 24-48 hours
Ensure adequate mineral content through GH boosters and specialized shrimp supplements; maintain stable water parameters; provide soft plants and hiding spots; perform gentle water changes with aged water
Muscular Necrosis (White Muscle Disease)
White discoloration in muscle tissue visible through translucent body; lethargy; loss of appetite; rapid decline
Increase water changes to 30-50% weekly; ensure adequate mineral supplementation (calcium, magnesium); maintain optimal pH 5.5-6.5 and temperature; improve diet with varied foods including blanched vegetables
Vorticella / Fungal Infection
White fuzzy coating on body or appendages; lethargy; difficulty moving; visible fungal growth
Perform 50% water change immediately; add Indian almond leaves or alder cones to provide tannins; increase aeration; maintain pristine water quality; avoid copper-based treatments as shrimp are extremely copper-sensitive
Copper Toxicity
Sudden death or severe lethargy; loss of color; convulsions; rapid decline in colony
Perform immediate 80% water change with copper-free water; check all medications, fertilizers, and tap water for copper content; use copper-free plant fertilizers; do not use any medications containing copper compounds
