How to Keep Cichlids With Crayfish

Cichlids are colorful freshwater fish native to Africa and South America. Crayfish are small freshwater lobster-like crustaceans. Because they're both freshwater, it seems you could keep the two together. However, both crayfish and cichlids are aggressive, and can be territorial. They are also both opportunistic feeders, and will eat each other if given the chance. Therefore, it's not recommended that you house the two together. However, if you are determined to keep them in the same aquarium, you can take some steps to make cohabitation possible.

Instructions

    • 1

      Place cichlids that are equal in size or larger than the crayfish in the aquarium. Crayfish are good at catching and eating any smaller fish in the aquarium.

    • 2

      Place cichlid breeds that are known to be less aggressive in the aquarium with the crayfish. Most cichlids are aggressive to some extent, but some types are less so, or may even be docile. Having less aggressive fish in the aquarium can make life easier and safer for the crayfish, which may end up as a snack for any hungry cichlids.

      Ensure that the water needs of the crayfish and cichlid types you choose are the same. Some crayfish are tropical, while others require cooler water. Different types of cichlids also need different water temperatures, flow rates and pH levels. The two species must have compatible needs in order to survive together.

    • 4

      Provide a large aquarium for the crayfish and cichlids. Cichlids are usually large fish, and need a lot of space. Crayfish require about 10 gallons of water for each specimen. With a large aquarium they may not run into each other as frequently. The actual size of the aquarium depends on the type and number of cichlids you're keeping, and how much space they usually need. The cohabitation aquarium should be at least several gallons larger than the space the cichlids usually require.

    • 5

      Place many decorations, such as hollow logs, rock structures and plants in the aquarium. These items will give the crayfish places to hide. Some of the decorations should have holes or entrances that are small enough for only the crayfish to climb in, so that hungry fish cannot disturb the crayfish.

      Feed the cichlids and crayfish often. Both species will be looking to make a meal out of their aquarium mates. Keeping them both well fed can sometimes curb the urge to hunt.
