yea its the same cray is just that when he moulted his claws got blue also when hes out of the water the camera changes his color alittle.
i dont have any more crays. yes your cray will go after you shrimp and cories and most likely catch them because the shrimp cant swim and the cories will eventually get tired of running and get eatin. did you goto bluecrayfish.com and join the forum?the only thing i can think of is like you said put him in the 12 gal and risking your other fish or just leave him where he is until you can get another tank or make space in your 12 gal.the forum will help you alot trust me.
