Posted for a friend... though, I've got two of the cute lil' buggers in my FW tank now.. they are quite comical to watch..
Electric blue crayfish (Procambarus alleni) for sale! Freshwater inverts,
prefer harder water or water supplemented with calcium (pH between 7.0-8.0
is best). They are best kept between 50-75 F., so a heater is not required,
but a filter or sponge filter is.
These crayfish will reach a maximum size of about 5-6" and live for about 3
years with proper care. I keep mine singly in 5 gallon tanks, as they are
pretty territorial as they grow up. They like hiding places during bright
sunlit hours - I use coconut shells and rock shelves for mine.
These guys will eat all types of food ranging from flake food to pellets to
lettuce. Keep it more on the vegetarian side w/cleaned egg shells for
calcium now and then. They can snag baby or slower/sick fish at night, but
are not great hunters. Some of these crayfish will eat your tastier plants,
and some just don't seem to bug the plants.
They are very fun to watch! These crayfish will grow very fast. Each molt
produces a stronger, deeper blue color, and they molt ~every 6-8 weeks for
me. As youngsters, they molt more often.
These striking creatures are currently about 1" long. They are $5/each at
this size. Shipping is extra, pickup is ideal (Sudbury, MA). Email me at
firstname.lastname@example.org if interested.
