Pinto Black Shrimp Breeding Guide
Breeding the black-base Pinto Black Taiwan Bee derivative of Caridina cantonensis: soft acidic low-TDS water, pattern selection, sexing, berried females and direct-developing shrimplets.
Overview
Pinto Black is the black-base counterpart of Pinto Red, a modern Taiwan Bee derivative of Caridina cantonensis with intricate spotted-head and body patterning. It is a direct developer like the rest of the species, hatching miniature adults from eggs, and requires the soft, low-mineral water shared by all Taiwan Bee lines.
As a highly selected pattern line it carries limited genetic diversity, so breeders work to fix the pinto markings while keeping the colony healthy.
Sexing
Females grow larger and develop a deeper abdomen for carrying eggs. Wikipedia describes females emitting pheromones when ready, after which males swim actively in search of a mate.
Conditioning
Maintain a mature, stable tank with soft, acidic water. The Shrimp Farm cites roughly 18-24 °C (65-75 °F) for bee-line Caridina, with regular light feeding of biofilm and prepared foods to keep females productive.
- Active substrate buffering pH below 7.0
- Remineralised RO water held at a low, stable TDS
- Guarded sponge filtration to protect shrimplets
Breeding Setup
Pinto Black needs soft, acidic Taiwan Bee water. The Shrimp Farm recommends GH around 4-6, KH 0-2 and a pH below 7.0 kept stable with remineralised RO water. A dedicated single-species tank prevents hybridising with other Caridina morphs and preserves the line.
Spawning & Berried Females
The berried female carries eggs beneath her abdomen, fanning them with the pleopods until they hatch. The Shrimp Farm gives about 30 days of incubation for bee-line Caridina, consistent with Wikipedia's roughly 28 days at about 22 °C.
Shrimplet/Larval Care
Pinto Black young hatch as tiny, fully formed shrimplets feeding independently on biofilm and detritus. They need only a mature, stable tank; their detailed patterning sharpens as they mature.
Common Challenges
The line is sensitive to TDS, pH and temperature instability, with Wikipedia noting that high temperatures cut egg survival. The added breeding challenge is selecting for clean spotted-head and body patterns over generations without weakening the colony through inbreeding.
