cool...
unfortunatly - our last male guppy (different tank) died yesturday (before i had chance to introduce them) - old age.
if she is pregnant - she started very young - when we got her she was only 5mm long! - is it likely
(the gravid bit does look dark to me, but i'm well out of practice with livebearers, I havent bread guppys for nearly 12 years!)
