I have/had some weird ones, I even posted on here and couldn't get a good id. I gave them to my roomie for his fish tank just to have some shrimp. I didn't want them to be a wild neo and get in to my red strain or anything. Sometimes the LFS just gets stuff in and puts into the generic shrimp tank. My LFS keeps yellows and reds together even, so you get a young one without much color, it can be a mix. One is really weird, I thought it was a sunkist orange, cause it was orange but it goes to an almost dark brown/black, clear, orange, light yellow, so I have no idea what it was, but it was berried in my roomies tank. The eggs were gone today after about 3 weeks or so, so have to wait and see if was a orange, they need brakish water, so I'll have to see in a few weeks if we see babies or not.
