Latin Name: Procambarus sp.Common Name(s): Hammers Cobalt Blue / Electric Blue Lobster / Blue CrayfishDifficulty: IntermediateTemperament: Opportunistic PredatorpH: 5.8 - 10Adult Full Size: 6"Minimum Tank Size: 30 gallonsPlant Safe: NoFoods: Sinking shrimp pelletsDescription: This is a species of ornamental crayfish, created through selective breeding, popular for their striking color which intensifies at they mature. Their coloration is not from a dye, and will never fade unless the animal is stressed. For this reason they may look brownish when they arrive in the package, but will regain color over the course of a week or so. They are opportunistic predators and as such cannot be mixed with other bottom dwelling fish in aquariums (like Cory catfish, loaches, plecos etc.) or slow-moving peaceful fish. Fast moving top-dwellers like danios, hatchets should be ok. They are aggressively territorial, so lots of room is needed to put 2 in a tank together (at least 20 gallons per lobster).
