Mystery fry id please

Hedging my bets...I'll give my answer in about three months, once provided with pictures of the lil' miracle at that point in time.
 
She got the plants from me, and from the stock in that tank, I would go with Pseudomugil furcata. Funny, because I have only one female left; the males died in Jan 09, and I sent her the plants around 2-3 wks ago.
 
A better pic would help, how big is it? I can't see the fins, but I think the red on the underside is a good clue. I have a golden danio and it never had any red on the underside like that. Maybe a golden killi, but I'm still leaning towards a young golden cloud.
Was it living without a heater? Why not try feeding it well and turning up the temp a bit and we will see what it looks like in a few more weeks. I love a good mystery.
