Ram ID and sexing.

Im upgrading my 40 gallon to a 70 gallon this month. I have been looking in to getting a small group of rams. Well this payday me and my other half had been out window shopping and ran across this little guy/girl.. lovely little fish.

Anyway...bought it and brought it home..it is now in QT in a 3.5 gallon tank..i think it is a bit cold for it so im going outside to look threw my bins for a small heater..soo got it yesterday(12/10/11) love its fines!

any Idea on sexing?
or what type it was? It was in a tank with allot of golden rams..but a few were the blues...could it be a mix of the two?

It paled out every time i pulled the cam up..so this is the best i can get for the moment.. maybe it will color up more with some heat and a few more days of good clean water and lots of food...it seems a bit thin to me.
(video to come soon as i can get it off my cam)
