The blue crayfish (scientific name Procambarus alleni, sometimes called the electric blue crayfish and the Florida cray) is a species of freshwater crayfish endemic to Florida in the United States. Its natural range is the area east of St. Johns River and all of Florida from Levy County and Marion County southwards, as well as on some of the Florida Keys.

It is included on the IUCN Red List as a species of Least Concern. The blue crayfish is frequently kept in freshwater aquaria. In the wild, this species varies from brown-tan to blue, but the aquarium strain has been selective bred to achieve a brilliant cobalt blue color.

They are a genetic oddity; a blue color morph of the common brown papershell crayfish. It is the lack of a gene that causes them to be blue. They were found in one location out of hundreds of ponds I have screened for bait fish. Currently I have taken a dozen blue crayfish and with the offspring I stocked in several ponds.

What do I feed crayfish?

Sinking pellets. My favorite is Tetra sinking mini-sticks for ornamental goldfish. There is a variety of sinking pellets on the market. Shrimp pellets and algae tabs are highly recommended. Frozen peas, canned carrots, green beans or slices of potato work real well. Feeder fish such as fathead minnows or rosy reds and even small goldfish. Do not feed them fresh shrimp, it carries a disease common to shrimp. They have a hard time catching the live fish, so injuring one to make it easier to catch is recommended.

Can my crayfish come out of the water?

Yes, they have been known to live out of water for weeks, as long they are kept damp. They need enough water to keep their gills wet. My 3 year old daughter loves to play with one in a small Tupperware dish with a touch of water in it.
