Comments
Many aquarists and especially kids mention that
they enjoy watching Crayfish, and Crayfish are fun
to watch. But Crayfish are quarrelsome and aggressive.
They will usually bother and sometimes eat Crabs,
Ghost Shrimp, Snails and Frogs.
Crayfish are covered
with an exoskeleton that is rigid and doesn't change
in shape by much. To grow larger the Crayfish shed
their exoskeletons, and for a day or two are covered
only with soft tissues which harden into a new exoskeleton.
You may see their old discarded exoskeleton on the
bottom of your aquarium, unless the Crayfish has
already eaten it to recycle the nutrients in the
exoskeleton.
Crayfish are also
called Crawdads.

Appropriate Home

Recommended Diet
Crayfish will eat virtually anything on the bottom
of the aquarium such as pieces of uneaten food,
Shrimps, Crabs, Snails, and Frogs. In this way they
help keep an aquarium clean, but they are not a
substitute for regular maintenance. Click

Compatibility
As mentioned above Crayfish generally make life
miserable for small animals living on the bottom
of their aquarium including other Crayfish. It seems
to be best to keep just one unless you have a large
aquarium. Crayfish usually cannot bother fish that
stay off the bottom.

of compatible fish.
