Freshwater crayfish are fascinating creatures and keeping them as pets can be a really fun hobby. However, if you plan on getting some tank mates for your pet crayfish, there are a few things you need to consider.
The Size of the Aquarium
If you are going to get your crayfish a few tank mates, you will need at least a 10 gallon aquarium. Anything smaller just won’t work. A tank smaller than 10 gallons is simply too small for a crayfish. Also a tank smaller than 10 gallons will not be efficient for filtering out toxins produced by the fish and the crayfish in the tank. Plus, for a crayfish, living in a fish tank that is smaller than 10 gallons would be like you living in your closet. – Not cool. So it goes without saying that the size of your crayfish’s fish tank is an essential part of freshwater crayfish are.
The Right Tank Mates
When finding the right tank mates for your crayfish, you will need to consider a few things. Mainly the fact that crayfish love to eat fish. – But that doesn’t mean every fish you put into the tank will become crayfish dinner. If you select the right fish, they should do just fine in the tank with your crayfish.
The right tank mates will be fish who swim near the top of the tank and/or are fast swimmers. Fish that swim on the bottom of the tank or swim slow are at a much higher risk of being caught and eaten by a crayfish. Some examples of good freshwater crayfish tank mates are hatchet fish, danios, red tail sharks and tiger barbs. I have all of these fish in my tank and I have zero problems.
As far as putting other crayfish into your tank, this can be iffy. Crayfish are very territorial and cannibalistic. They have absolutely no problem eating their brother. If you have a 10 gallon tank, I advise you to only put one more crayfish into your tank if at all. Personally I think one crayfish is ideal for a 10 gallon tank. I’ve already gone through the whole ordeal of having two crayfish in my tank. It was fine at first, but eventually one of the crayfish ate the other. It was kind of ugly.
Remember, having tank mates for your crayfish can be cool, but isn’t required for proper freshwater crayfish care.
