Well i guess i figured out wheter or not my cray was a marble or not as she has had he first (that i know of) batch of eggs. I can tell that they are fertile (i owned a few crays before including about 1000 marmors) and i am guessing it is probably one of her first (she is still really small and the berry is really small too). I don't expect too many of the babies to survive because of the danios, and serpae tetras (the danios are starting to look nice a pregnant also) but i am sure a few will manage to find somewhere to hide and survive.
