Blue Bolt Pinto Shrimp

Caridina logemanni

Also known as Blue Bolt Pinto, Pinto Shrimp Blue Bolt

Animalia›Arthropoda›Malacostraca›Decapoda›Atyidae

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

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
