Red Galaxy Pinto Shrimp
Caridina logemanni
📍 Taiwan / Germany selective breeding
Red Galaxy Pinto Shrimp are a selectively bred Caridina variety featuring striking red coloration with black or dark pinto (spotted/patched) patterns across the body and legs. This dramatic contrast makes them highly sought after by advanced hobbyists. The intensity of red pigmentation and pattern definition depends on water parameters and diet quality.
Care Guide
Diet
Red Galaxy Pintos are detritivores that graze on biofilm, algae, and decaying plant matter. Supplement 2-3 times weekly with specialized Caridina foods (Shirakura, Mosura, Benibachi) and blanched vegetables like spinach or zucchini. High-quality mineral-rich foods enhance color intensity and pattern definition.
Behavior
These shrimp are active grazers, constantly foraging along substrate and plants. They molt regularly; provide plenty of hiding spots and leaf litter for security during vulnerable molting periods. Colony dynamics are peaceful with minimal aggression; they thrive in groups of 10 or more.
Breeding
Red Galaxy Pintos require soft, acidic water (pH 5.5-6.5, GH 4-6) to breed successfully. Females produce small batches of 20-30 shrimplets that develop fully in the mother's pouch before release as miniature adults. Breeding is moderately difficult and demands stable parameters; fry are hardy once released.
Tank Mates
Small, peaceful algae eater that does not prey on shrimp
Tiny, non-aggressive fish; may occasionally nip at shrimp but generally compatible
Nano fish that shares similar water parameters and peaceful temperament
Larger shrimp species; may compete for food but generally coexist peacefully
Provides grazing surface, shelter, and biofilm production
Common Diseases
Molting Failure / Incomplete Molt
Shrimp stuck in exoskeleton, inability to shed completely, lethargy, death within 24-48 hours
Ensure adequate mineral content via GH boosters (Salty Shrimp GH+); maintain stable pH and temperature; provide leaf litter and hiding spots; increase water change frequency to 25% weekly
Muscular Necrosis (MSN)
White/opaque patches on muscle tissue, loss of color, lethargy, refusal to eat, rapid decline
Increase water changes to 50% twice weekly; boost mineral supplementation; ensure TDS 100-150; add Indian almond leaves for tannins; isolate affected individuals if possible
Vorticella / Protozoan Infection
White fuzzy coating on body/antennae, lethargy, difficulty molting, cloudy appearance
Perform 50% water change; add Indian almond leaves or alder cones for tannins; increase aeration; maintain pristine water quality; avoid copper-based treatments (lethal to shrimp)
Copper Toxicity
Sudden death, erratic swimming, color loss, paralysis
Immediately perform 80% water change; use RO or distilled water; check all fertilizers and medications for copper content; use copper-free plant fertilizers and medications only
