Talk:Atyopsis moluccensis

Does anybody know the diffrence?
Does anybody know thediffrence between Atyopsis moluccensis and Atyopsis spinipes, except they're size? In a local shop there are two filter shrimp, and i don't know if they're moluccensis or spinipes. They don't have any food there so they pick the bottom. and another question is a 54 l aquarium enough for two spinipes, I have food for them, i just want to know if it's enough for them.
