Keri Anne Posted January 29, 2006 Report Share Posted January 29, 2006 Does anybody know how long it take for the gravid spot of a virgin female guppy to darken after mating? (In other words how long until I know if the Female Albino guppy I have in the breeding tank is fertile or not?) Yes I know, it's been little over a week, I should just wait. :oops: Quote Link to comment Share on other sites More sharing options...
Alan Posted January 29, 2006 Report Share Posted January 29, 2006 I doubt it will go black KA. Being an albino, and if she's up the ummm preggo, I would expect the colouration to be of a golden colour. Alan 104 Quote Link to comment Share on other sites More sharing options...
shiuh Posted January 30, 2006 Report Share Posted January 30, 2006 yup. agree with Alan. Albino offsprings dont have black pigment in their gene. if you see a dark gravid or see little black eyes in their gravid. chances are there are no albino babies at all. what you want is blonde gravid spot i suppose.

alanmin4304 Posted January 30, 2006 Report Share Posted January 30, 2006 If you crossed it to a normal the gravid spot will be dark as the young will be all normal split to albino. Quote Link to comment Share on other sites More sharing options...
Keri Anne Posted January 30, 2006 Author Report Share Posted January 30, 2006 Was crossed to a normal, so unless he caries the albino gene (unlikely) it should darken, right? Quote Link to comment Share on other sites More sharing options...
