Marbled Crayfish

About

Found in the freshwater systems of Papua New Guinea and parts of Australia, Cherax peknyi is a large, ornate crayfish that has built a solid following among invertebrate keepers. Often sold under trade names like the Marbled Crayfish or the MacRobertson's Land Crayfish, this species is best known for the dramatic patterning and coloration that can vary considerably between individuals. Some displaying rich blues and oranges, others leaning toward earthy browns and creams. Like most cherax crayfish, it is a reasonably hardy animal once settled, but it earns its intermediate care rating through its size, its occasional aggression toward tankmates, and its tendency to rearrange decor and uproot plants whenever the mood strikes. Keeping it with fish requires some thought, as smaller, slower species are at risk of becoming a midnight snack. Giving it plenty of hiding spots, caves, pipes, driftwood, goes a long way toward keeping it settled and reducing territorial disputes, especially if you're housing more than one. It's a rewarding species for keepers who appreciate invertebrates with genuine character, and watching one work through its environment with those dexterous claws never really gets old.
