Spotted Head Pinto Shrimp
Caridina logemanni
📍 Taiwan selective breeding
The Spotted Head Pinto Shrimp is a selectively bred Caridina variety featuring distinctive white or cream-colored spots concentrated on the head and body, creating a striking contrast against a darker base coloration. This pinto pattern makes them highly sought after by enthusiasts who appreciate intricate markings. They are small, peaceful bottom-dwellers ideal for planted nano aquariums.
Care Guide
Diet
Spotted Head Pinto Shrimp are detritivores that graze on biofilm, algae, and decaying plant matter throughout the day. Supplement with high-quality shrimp foods such as Shirakura or Mosura pellets 2-3 times weekly, and offer blanched vegetables like spinach or zucchini occasionally. Ensure adequate mineral content through specialized Caridina supplements to support molting and coloration.
Behavior
These shrimp are active grazers that spend most of their time foraging on substrate and plants. They are social and thrive in colonies, exhibiting natural hierarchies without aggression. Molting occurs every 4-6 weeks; provide plenty of hiding spots and leaf litter to support successful molts and reduce stress during vulnerable periods.
Breeding
Spotted Head Pinto Shrimp require soft, acidic water (pH 5.5-6.5, GH 4-6) to breed successfully, as harder water inhibits reproduction. Females produce small batches of 20-30 shrimplets that develop within the mother's saddle; no planktonic larval stage occurs. Offspring are miniature versions of adults and require stable parameters and abundant biofilm for survival.
Tank Mates
Small, peaceful algae-eater that shares bottom-dwelling niche without competing aggressively
Tiny, non-predatory fish that coexist peacefully in planted tanks
Nano fish with similar water parameter requirements and peaceful temperament
Larger shrimp species that can cohabitate if tank is spacious; may compete for food
Provides essential biofilm, hiding spots, and grazing surfaces for shrimp
Low-light plant that creates habitat structure and supports biofilm growth
Common Diseases
Molting Failure / Incomplete Molt
Shrimp unable to shed exoskeleton completely, becoming stuck or dying during molt; lethargy and loss of appetite
Increase mineral content through specialized Caridina supplements (GH Booster, Salty Shrimp Mineral); maintain stable pH 5.5-6.5 and adequate calcium; ensure low nitrate levels and perform 25% water changes weekly
Muscular Necrosis (Wobble Disease)
Shrimp exhibit uncoordinated swimming, trembling legs, loss of grip, and eventual paralysis; typically affects newly imported or stressed individuals
Improve water quality with frequent small water changes; add Indian almond leaves and peat moss for tannins; ensure stable temperature 22-24 C; reduce stress by providing dense vegetation and hiding spots; quarantine affected individuals
Vorticella / Fungal Infection
White fuzzy coating on body or appendages; lethargy; difficulty molting; visible fungal growth on antennae or legs
Perform 50% water change and increase aeration; add Indian almond leaves for tannins; maintain pristine water parameters; remove affected shrimp to quarantine if infection spreads; avoid copper-based treatments (lethal to shrimp)
Copper Toxicity
Sudden death or severe lethargy; loss of appetite; discoloration; gill damage; occurs from copper in medications or tap water
Use only copper-free medications and supplements; test tap water for copper content; perform immediate 50% water change with RO or distilled water; use activated carbon in filter; do not treat with standard aquarium medications containing copper
