Three spots can be quite aggresive, how bigs the tank? The bigger the tank, the better, these fish need their own territory to feel secure, so plants/decorations/wood is a must.
If the color of the picture is correct, it looks more pink than gold to me. Are you seeing any blue when it flares? If so, my guess is that it's a platinum gourami.
And if does look like it's a female. Does it have a rounded belly when viewed from above? If so, it is a female.
These can be very beautiful fish, and might well be my favorites as far as coloration goes, but they can be quite nasty as well. I had one platinum male who was so mean that I had to banish him to the goldfish tank.
A 3 spot is called that because it has 3 spots on its body. One is just in front of its tail, the second is about half way down its body and the third is its eye. It's usually the blue gouramis that show these markings though.
... the pic is bad quality no blue on it whatsoever. that is just shadowing. its a yellow colour with a whiter belly. cant see the two wpots on her either, i can safely say she has an eye though ill try and get some more pics in better focus so u can see the patterns on her.
