Blue Dwarf Cajun Crayfish
Tank Requirements
Many adult size crayfish can live in a 10 gallon setup. You should always have plenty of hiding places for the crays to find refuge. The babies too require many hiding places. If there is not sufficient hiding places they will eat each other during molts. They are compatible with many small fish such as, neon tetras, mollies, guppies, platys, swordtails and small catfish. They can be kept without a heater. They will not eat plants or burrow in your rocks. They are not compatible with larger fish as they may become fish food!
Breeding
Breeding can happen as early as 1” in size. Male will pin female on her back to transfer sperm which the female can hold onto the sperm for long periods of time until she feels it’s safe to extract her eggs. If kept under the right conditions the cajun dwarf crayfish will produce between 30-40 eggs, Eggs take approx 30 days to hatch. young are then carried around for another day or two before they start exploring the tank. The parents usually leave the offspring alone as long as enough tank space and enough hiding spaces are provided.
Feeding
Crayfish are scavengers & will eat whatever they find. I supplement their diet with several types of commercially available foods commonly found at most pet stores. As their staple diet I use 100% pure spirulina flake. I also use algae wafers or pellets that are high in spirulina. To mix things up a bit I will give them some fresh vegetables from time to time such as, spinach, peas, or zuccinni. I blanch the spinach prior to feeding the crays to clean and help it sink to the bottom.
