The short answer
Cherry shrimp are one of the easiest animals in the hobby to breed — you mostly just leave them alone. In a stable, mature, well-fed tank with a mix of males and females, a colony breeds continuously without any intervention. There’s no pairing, conditioning or spawning trigger to manage; your job is simply to keep conditions steady and give the babies somewhere to hide.
What makes them breed
The single biggest factor is stability. Cherry shrimp thrive when temperature, pH and hardness stay consistent and the tank is biologically mature (well past its cycle, with a healthy film of algae and biofilm to graze). Aim for a stable temperature around 22–25°C and avoid big swings. A mature female will carry a clutch of eggs — she’s then called “berried” — fanning them under her tail for roughly three weeks before releasing fully-formed miniature shrimp.

Protecting the shrimplets
Baby shrimp are minuscule and defenceless. To grow the colony:
- Add dense plants and moss — Java moss is ideal, giving shrimplets endless cover and biofilm to graze.
- Keep fish out, or choose tiny peaceful ones. Even small fish pick off shrimplets; a species-only shrimp tank is the reliable route.
- Avoid a strong intake. Sponge-covered filter inlets stop babies being sucked in.
Feeding for a growing colony
An established tank supplies a lot of natural food, but supplement lightly with quality shrimp food, blanched vegetables and biofilm boosters. Don’t overfeed — leftover food fouls the water that stability depends on. See our food picks and, for more on raising the young, how do I protect baby shrimp.
