Having crayfish, freshwater species in your tank can add a balance to the environment. These are scavenging creatures so they will aid in keeping the aquarium clean. You have several varieties to choose from. The colors of the Blue Dwarf Crayfish or the Bright Orange Crayfish will add vibrancy and excitement to any aquarium. The Dwarf Crayfish is non-aggressive and can be kept safely with other species of crayfish or even shrimp. Crayfish can live in any freshwater but putting a species into a tank that is already established is best.

Regardless of the species you choose you should remember to place a tightly fitting lid on the tank as they will sometimes climb out and they can’t survive without water for too long. You will also need to supplement their diet as the debris in a well-functioning tank will soon run out. One of the most popular ways to supplement is with Hikari Algae wafers or with Hikari Crab Cuisine.
