CPO Crayfish feature a beautiful and eye-catching blue coloration that will add a burst of color to your tank! Dwarf crayfish like these are one of our favorite invertebrates here at Aquatic Arts. They are much larger in size than dwarf shrimp when fully grown (they can grow up to 1.6 inches long) and tend to live much longer, but are still small enough to comfortably live in a tank as small as 5 gallons. They are one of the most brightly colored varieties of invertebrates we offer, and their large size draws the eye right to them. Additionally, they are easy to care for, and their feeding requirements are simple - they feed on leftover food or almost any kind of fish food.
These are quite active and do not hide during the day like most crayfish. They make an exciting addition to any aquarium, and they're a great way to get into invertebrates if you haven't joined the craze already!
Though the CPO Crayfish is small enough not to be a threat to most other tank inhabitants, they have on occasion gone after dwarf shrimp, so we don't recommend keeping them in the same tank. As with any crayfish, the golden rule is that if they can catch it they may try to eat it. These are normally peaceful, but all crayfish are opportunistic omnivore hunters/scavengers so there is always a small chance they could try to fin clip slow-moving fish or ones with long flowing fins. We have kept them with schools of fast-moving small fish like rasboras, rainbowfish, and danios with very little to no issues. Caution just needs to be advised whenever housing a crayfish with other tank mates.
