Very nice gymnos! Amazing colors...
According to Ken females are supposed to show a lot more yellow. Should be easier to tell if you have males and females in the same tank.
This is a different species but just to give you an idea: female on the right and male on the left.

Thanks for the info!!! Is there a certain size when these differences become apparent? Also what species are your gymnos?
They are G. n.sp. "Sarandi". Sorry I got it backwards - female on the left and male on the right.
Pretty fish!!! After looking online and at your pics I noticed that our fish look pretty similar. Is there anyway to distinguish morphological differences betwen G. norte, G. Sarandi, and even G. rhabdotus?
that exactly it - almost impossible to tell without knowing the locality. The good part is...have one, have all 
Those aren't three species. They're all fish in the "rhabdotus" complex (substrate spawning Gymnogeophagus) that vary by geographic varient.
Felipe Cantera's website is the best source: www.aqvaterra.com
It's REALLY important that people don't mix different Gymnogeos by locality if they're going to breed them / pass of the fry.

Hey thanks for the site!!!
My only question is I have G. norte and the site doesn't have them listed under the rhabdotus complex so are my fish from a region north of Urugauy or one of the subspecies found in the Northern part of Uruguay? Thanks!!!
One of the species found in northern part of Uruguay. 'Norte' is a trade name rather than a specific location name, though not sure which one they much up to on Felipe's site.
