Cherax boesemani. Not to be mistaken for the popular dwarf CPO or Mexican Dwarf. This variety gets large (Up to 4-5" in the body) and keeps the intense orange colour. While you can try keeping crayfish with fast, surface oriented fish such as danios, always bear in mind that crays will eat whatever they can get their claws on!
These are young adults about 2-2.5" long in the body.
