Galaxy Pinto Shrimp
Caridina logemanni
Also known as Galaxy Pinto
Animalia›Arthropoda›Malacostraca›Decapoda›Atyidae
Galaxy Pinto Shrimp are a stunning selectively bred variety of Caridina logemanni, characterized by a deep black or dark base coloration heavily speckled with white, cream, or iridescent spots resembling a galaxy pattern. This striking contrast makes them highly sought after by advanced aquarists. The intricate patterning and coloration intensity depend on water parameters and diet quality.

Care
Diet
Galaxy Pinto Shrimp are detritivores that thrive on biofilm, algae, and decaying plant matter. Supplement with high-quality specialized shrimp foods such as Shirakura, Mosura, or Benibachi products designed for Caridina species. Occasional blanched vegetables like spinach, zucchini, or sweet potato enhance nutrition and coloration.
Behavior
These shrimp are active grazers, constantly foraging along the substrate and plants for food. They are social and do best in groups, displaying natural colony dynamics with minimal aggression. Molting is frequent and essential; provide plenty of hiding spots and mineral-rich water to support successful molts.
Breeding
Galaxy Pinto Shrimp require stable, soft acidic water (pH 5.5-6.5, GH 4-6) to breed successfully. Females produce small batches of 20-30 shrimplets that are born fully formed (no planktonic larval stage). Breeding is moderately difficult and demands pristine water conditions, consistent temperature, and excellent nutrition for females.

Common diseases 4Molting Failure / Incomplete Molt, Muscular Necrosis (MSN), Vorticella / Fungal Infection, Copper Toxicity
Molting Failure / Incomplete Molt
Shrimp stuck in old exoskeleton, inability to shed completely, lethargy, death if untreated
Increase mineral content via GH boosters (Salty Shrimp GH+), ensure adequate calcium and magnesium, maintain stable pH and temperature, provide soft plants for grip during molt
Muscular Necrosis (MSN)
White spots or patches on body, muscle tissue discoloration, lethargy, loss of appetite
Perform 30% water changes, increase aeration, ensure TDS 100-150 ppm, supplement with mineral-rich foods, maintain optimal pH 5.5-6.5 and temperature stability
Vorticella / Fungal Infection
White fuzzy coating on body or appendages, lethargy, difficulty moving
Increase water changes (25-30% every 2-3 days), add Indian almond leaves or alder cones for tannins, maintain excellent water quality, avoid copper-based treatments (toxic to shrimp)
Copper Toxicity
Sudden death, erratic swimming, loss of color, paralysis
Perform immediate large water change (50%), use copper-free medications only, check all fertilizers and supplements for copper content, use RO water if tap water is copper-contaminated
