I got this at a GSAS meeting (greater seattle aquarium society) and believe it or not, I forgot the name. I tried to contact the guy who sold it but I guess he sold a bunch of different species of killies that he doesn't know and I have forgotten his email when I finally took pictures today.

I used to have a female that was grey but she either, jumped, died because of the filter intake or was eaten by my betta. Here he is:

You have a South American annual of the Genus Simpsonichthys. Could be boitoni, but I'd guess santanae. Pretty fish.

Thank you! I will look at pictures.
