Hey everyone. Was looking at options today to add to a 12 gal that has 5 Blue Velvet Shrimp (essentially RCS). I am thinking about some of the smaller Killifish due to the small tank and compatibility. Would a pair of Aphyosemion (probably bitaeniatum or bivittatum) be ok with shrimp. I know...

Could someone tell me what species this fish is? I'm assuming it's in the genus Aphyosemion, but I'd like to know the exact species, if possible.
