Princess Bee Shrimp Breeding Guide (Paracaridina)

Breeding the Princess Bee shrimp (Paracaridina cf. zhejiangensis): a soft-water freshwater direct developer that carries eggs under the abdomen and releases miniature shrimplets, hatching in about 28 days at 22 C.

Overview

The Princess Bee is a small Chinese Paracaridina shrimp (Paracaridina cf. zhejiangensis) in the family Atyidae, with a delicate brown-and-red banded pattern. Care sits between hardy Neocaridina and high-grade bee shrimp. Like other bee-type shrimp it is a soft-water freshwater breeder: eggs are carried under the female's abdomen and hatch into miniature shrimplets, so no brackish or salt stage is involved, placing it among the more accessible dwarf shrimp to reproduce once water is right.

Conditioning

Match the soft, slightly acidic water that bee-type shrimp evolved in. Bee shrimp do best in relatively soft, slightly acidic water and dislike heat; a useful guide is keeping temperatures between roughly 16.5 and 24.5 C, with the strongest colour often developing around 24-25 C. Provide mature biofilm, leaf litter and detritus, feed lightly, and keep nutrients low. Stable, well-aged water is the main lever for bringing a colony into breeding condition.

Breeding Setup

A small, biologically mature planted species tank suits this dwarf shrimp; the record's 20-litre minimum is ample for a starter colony. Soft acidic-to-neutral water held stable, plenty of moss and grazing surface, and gentle mature filtration encourage continuous low-level breeding. As a freshwater direct developer it needs no separate rearing vessel, so the breeding tank doubles as the grow-out tank.

Spawning & Berried Females

Bee-type shrimp breed in freshwater and are fairly prolific. The female carries the eggs beneath her abdomen, fanning them with the pleopods; at about 22 C the expected hatching time is around 28 days. The Princess Bee follows this pattern as a direct developer, releasing fully formed young rather than free-swimming larvae, so a settled female can produce successive broods in stable conditions.

Shrimplet/Larval Care

Hatchlings emerge as miniature adults and require no brackish phase; they graze the same biofilm, detritus and leaf litter as the parents from the first day. Dense moss and aged substrate supply the microfauna and shelter small shrimplets need. Keep parameters steady and avoid copper and untested medications, which are especially hazardous to young shrimp.

Common Challenges

The main demand is providing and holding soft, slightly acidic water at a moderate temperature rather than the hard alkaline conditions some other shrimp need. Avoid warmth above the mid-20s C, which bee-type shrimp tolerate poorly, and keep fish or larger shrimp that would prey on shrimplets out of the colony. With stable water the species reproduces steadily.
