Mystery fry id please

Has anyone suggested the much requested poo-eating fish yet?
 
Guppy or Killie. I lean towards Guppy but the fact that you've added nothing to the tank in a month leads me to believe it's some kind of killie. It really looks like an undernourished Guppy of about a month old.
 
no but really looks like a lil celebes rainbow
 
My guess is still pseudomugil gertrudae.
 
Its green, I say call it a grinch fish!! lol
