The Crayfish, Not the Restaurant
Keeping an aquarium doesn’t necessarily mean keeping fish. The box of glass and water can be used for keeping other interesting creatures instead…such as crayfish! These aren’t the crayfish of your childhood creek bed: these creatures are bright and very colorful. For the home aquarium, they are often referred to as lobsters rather than crayfish, but they are a freshwater crayfish. Two examples are the Electric Blue Lobster and the Neon Red Lobster, which are both beautifully colored. These freshwater inverts are gorgeous, with plenty of interesting behavior to observe, easy to care for, and very easy to feed, making a smaller size aquarium of 20 gallons along with one of the lobsters an excellent choice for a situation such as a science classroom in a school or in a house with kids who are curious about animals and biology.
Setting up a habitat for a crayfish is rather straightforward. Start with either fine sand, or small fine gravel because crayfish do like to dig and burrow. Add in some driftwood, or artificial decorations to form cave-like areas for hiding and the terrain will be suitable. Combine that with a PH in the middle 7’s and a cool water temperature of 65 to 72 degrees, and you will have good conditions to keep a crayfish as a pet. They are territorial, so if the habitat is relatively small, then keeping only one is preferred.
them. Some sources also state that offering them a small leaf of romaine lettuce from time to time will help to vary their diet.
Average lifespan for either of these interesting creatures is approximately 5 years.
