Blue Bolt Pinto Shrimp
Caridina logemanni
📍 Taiwan selective breeding
The Blue Bolt Pinto Shrimp is a striking selectively bred variety featuring a bold pattern of solid blue coloration interspersed with white or cream-colored sections, creating a distinctive 'pinto' or patched appearance. This variety combines the vibrant blue pigmentation of Blue Bolt shrimp with the irregular patterning characteristic of Pinto genetics, making each individual uniquely marked. Highly prized by advanced hobbyists for their spectacular coloration and complex care requirements.
Care Guide
Diet
Blue Bolt Pinto Shrimp are detritivores that graze on biofilm and algae throughout the day. Supplement with high-quality shrimp-specific foods such as Shirakura, Mosura, or Benibachi pellets 2-3 times weekly. Occasional blanched vegetables like spinach or zucchini can be offered, but remove uneaten portions within 24 hours to prevent water quality degradation.
Behavior
These shrimp are primarily nocturnal grazers, spending most of their time foraging along substrate and plant surfaces. They are generally solitary but tolerate colony living; molting occurs every 4-6 weeks and shrimp become vulnerable during this period. Males may display mild aggression toward each other, but serious injury is rare in adequately sized tanks with sufficient hiding spaces.
Breeding
Blue Bolt Pinto Shrimp require stable, soft acidic water (pH 5.5-6.5, GH 4-6) to successfully breed and maintain color intensity. Females produce small clutches of 20-30 shrimplets that develop fully in the mother's pouch before release as miniature adults. Breeding success depends heavily on pristine water conditions and consistent mineral supplementation; even slight pH or hardness fluctuations can result in failed molts or color degradation in offspring.
Tank Mates
Small, peaceful algae eater that shares bottom zone without competing for food or harassing shrimp
Tiny, non-aggressive fish that occupy mid-water column and pose minimal predation risk to adult shrimp
Extremely small and peaceful; occupy different water zones and do not prey on shrimp
Can be kept together but may compete for food and space; larger Amano may occasionally harass smaller Pinto shrimp
Provides essential grazing surface, shelter during molting, and biofilm production for nutrition
Hardy plant that creates hiding spaces and supports biofilm growth without being uprooted by shrimp activity
Common Diseases
Molting Failure / Incomplete Molt
Shrimp unable to fully shed exoskeleton, becoming stuck or dying during molt; often preceded by lethargy and loss of appetite
Increase mineral supplementation (GH Booster, Salty Shrimp GH+) to 4-6 dGH; ensure pH stability at 5.5-6.5; perform 25% water changes weekly; provide abundant hiding spaces to reduce stress during vulnerable molting period
Muscular Necrosis (Black Death)
Black or dark discoloration on legs, body, or tail; progressive muscle deterioration; lethargy and refusal to eat; rapid death within days
Immediately perform 50% water change with aged water matching tank parameters; increase aeration; add Indian almond leaves or tannin-rich botanicals to lower pH and provide antimicrobial properties; isolate affected individuals if possible; maintain pristine water quality with frequent partial changes
Vorticella / Fungal Infection
White fuzzy coating on body or appendages; cloudy appearance; lethargy; difficulty molting
Perform daily 30% water changes; increase water flow and aeration; add Indian almond leaves or oak leaves for tannins; avoid copper-based treatments (lethal to shrimp); maintain temperature at 22-24 C; ensure biofilm-rich environment for immune support
Copper Toxicity
Sudden death or paralysis; erratic swimming; loss of color intensity; inability to molt
Immediately perform 75% water change with copper-free water; check all supplements, medications, and equipment for copper content; use only shrimp-safe plant fertilizers and medications; never use fish medications containing copper; maintain activated carbon in filter if copper exposure suspected
