Crayfish and lobsters can be found in a variety of cooler waters, and there have been some problems with crayfish making an overpowering appearance outside of their native waters. For that reason certain species can be hard to find in aquatics centres, and you may need a licence to keep non-native specimens. All varieties sport glorious colours, they are however best kept in a specimen or species aquarium. Their aquarium should be furnished with rocks and plastic plants and roots as real plants will be destroyed. If more than one crayfish is to be kept in a tank they will need a lot of space as they are both territorial and cannibalistic. Also after a cray has moulted it becomes very vulnerable, if it is kept with anything that may attack it (like another crayfish) then the cray should be removed/separated until the carapace hardens. Crayfish are nocturnal and are best viewed after lights out, they should also be fed around lights out until they adopt a diurnal existence. They will readily hand feed once settled. Feed an omnivorous diet, including shrimp pellets, small fish, lean meats, worms, cockles and other frozen foods. Any uneaten food should be removed quite quickly as they have a tendency to hide hoards of food.
Crayfish reproduce using the specialised method of Breeding.
