Females often carry eggs in captivity, but the larvae go through a complex life cycle and are extremely hard to raise, so it is unlikely to breed in a home paludarium.
Not practical.
Brackish paludarium.
Gravid female released.
Hundreds of eggs.
Planktonic larvae.
One breeding tank for the red claw crab, drawn to scale from the breeding guide.
Water: 24–27 °C · pH 7.5–8.5
A plan from the breeding guide and an adult size of 5 cm. Tank shape is a standard 2 : 1 : 1.2 box, at least 6 adult lengths long. Check each step in the guide above.
A rack of breeding and grow-out tanks.
The breeding guide gives no tank size for the red claw crab yet, so a business layout can't be drawn.
Females have a much wider, oval belly flap (pleon); males have a narrow, pointed one and usually larger, brighter claws.

These need brackish or sea water to raise. Not a beginner project.
Surviving young are slowly moved back to fresh water.
