okay i did find something about how it is possible to have both genitals but wouldnt they need to be fertilized? Or i seen if its a marble crawfish then there doesnt even need to be 2 sexes but i dont think that is it...hummm....i guess ill just have to wait and see if the second one hatches and if so then figure out why when i bought them only one had eggs...even reading on them it said that the male first lays a ball that looks like cotton before the female passes the eggs through the sperm to lay them there but when we bought them the second one did not even have a cotton ball....could it be a mother mary crawfish ????lol
