dark green and undeer the tail,
chance of survival 0.00000000000000000001% give or take a couple of points, in an aquarium(thus the price, if they had a good survival rate, the price would drop)
unless, you have another system set up and ready for them, with no filters or anything esp. fish, that could eat them, sorry but very few ever make it, and they can reproduce everycouple of weeks(each time they molt, they release and fertilize the eggs
i may be wrong, but ours have reproduced many times, and have none yet, & we were told to have much of a chance that you do need a seperate tank ready for them
