Hi , I bought one coral banded shrimp thinking it was a male, it was small and skinny, it would only come out at night. Then few months later I bought another one thinking it was a female, since it wasn't skinny, and had a yellowish abdomen. After introduction to the tank, the older banded coral shrimp started to come out, to my surprise, it had molted and was a bit bigger than the one I just bought, I noticed it was not that skinny, and the abdomen was yellowish too. Both coral banded shrimp, have transluscent yellowish abdomen. If I look from under them, I see only transluscent yellow. Here is a picture of one of them, they both look the same I knew female coral banded shrimps were supposed to have greenish, blueish bellies. Well, the ones I have, both have yellowish translucent bellies, not actually green or blueish transparent ones. The older one was attacking the new one, the new one lost many arms, so I changed it to the fuge, thinking otherwise it would die. After I changed the new one to the fuge, it shed its old skin right away. And then I saw it not completely molted, and it was more transparent, Then I saw its torso that now was greenish instead of yellowish. I took a picture. So, is it a male or a female?. Could a male also have this greenish color? I have heard that is almost imposible to form a couple in a normal aquarium, but other people say they have been succesful, and I don't know if I should give it a try.
