Thanks for the bump tropics! However, the scientific name for these particular crays is Procambarus alleni and they are found in Florida and in the wild are brown. These crays will do nicely in a 10g aquarium as long as they have hides to get into to feel secure. You can also divide the 10g aquariums into two sections as they do not need much space in which to live, They are moderately-aggressive and will cannibalize each other if the cannot get out of each others way and this behavior is present at birth-lessens a bit as juveniles and returns when sexually mature. These crays are all sexually mature and I have raised them. They are not a community-dependant decapod so they will be quite happy with no other crays around. Although the size is generally referred to as getting to be 7-8 inches many captive bred crays do not get that large. This type of cray will breed all year round and they eat many things as they are not choosy! If you feed live foods these can help keep your tank clean as they will scavenge the bottom of the tank. I feed mine Hikari sinking carnivore pellets, carrots, peas, earthworms, wax worms, dead fish, live fish, frozen blood worms, marimo balls, duckweed (their favorite!), mosses, anacharis, snails, live white worms (very funny to see them eat these!) squash, white and sweet potoatos, green beans, etc., basically anything they can get little claws onto!
They are fun crittersto have!!! I need to clear out some tank space as I have some dwarf crays that need space, that is why I am selling them now. If I didn't need the space--They woulld all be kept as I really enjoy them.
