Overview

The Florida blue crayfish owes its very bright coat to a selected form: wild populations are rather brownish. Males are larger with narrower claws, while females are stockier.

Scientific name
Procambarus alleni (Faxon, 1884)
Classification
Decapoda › Cambaridae
IUCN Red List
Least concern (LC)

Natural habitat

United States: Florida

Observations (GBIF) and localities Native countries Rivers and lakes

It lives in water of 18 to 30 °C, slightly alkaline (pH 7.5 to 8), over sand and humus. Wild populations are rather brown: the bright blue coat is a selected form.

Behaviour

Nocturnal, it lives in small groups on the bottom and is rather calm, but tolerates no intrusion into its territory and can fight its territorial neighbours fiercely.

In the aquarium

Care and setup

Prefer a species aquarium with caves and separate refuges. It may attack fish and crustaceans and damage plants. Keeping adults together remains risky, especially males.

Feeding

The source describes it as omnivorous; give varied food on the bottom.

Breeding

It breeds in fresh water. Cannibalism means a great many shelters are needed to have any hope of keeping the young.
