breeding guppys?

Question

I have a regular customer at the pet store I work at and I can not figure out why her female guppys die after having their babys.The babys are fine and her water checks out ok ,so she says.I tell her to keep her PH at about 7 to 7.2.Im puzzled, any ideas?Thanks for the feed back.

Answer 1

Could the females be a bit young? That's often the cause of delivery related deaths. Possibly the strain is highly inbred and the fish are a bit fragile or the babies a bit too large? Maybe you could help her get a few fish from another customer that's breeding guppies and let her mix in a new line to see if that helps.

Answer 2

are the female guppies fully mature, maybe they are having difficulties in giving birth, and it is a trapped baby dieing and causing infection that is causing the mother to die.

I once kept guppies and the problem was not breeding them it was trying to stop them breeding.

1 female can have 3 litterers of 100 fry (babies) having only matted once.

guppies are a fairly easy fish to keep, so it might not be tank conditions killing the fish.

I would find out if the females are fully grown before matting, If not I'd advise that the owner allow the guppies to grown to full size as young fish then consider breeding them. Guppies grow up pretty fast
