Guppys

[RobbieM]

I tought guppys were ment to give birth every month, mine has again after 3 weeks?
Ive had to let a few of the last lot into the main tank as the net was too crowded, shes had a few more and i caught a few loose in the tank.
Only problem is my shark is hunting and eating the 3 week old fry. Ive tryed turning the light out but then they all swim to the end where the lights comes in from outside and make themselfs sitting ducks. Nitemare

Guppies can give birth every 21-35 days plus or minus a few days. Guppies are not big enough to put in a main tank and survive until they are about 1 inch in size. That's about 3 months in age. Add lots of plants so they can hide both floating and anchored if you want some to survive. HTH

Increasing the temperature or having higer temps will increase developement in the womb, therefor fry will be born quicker.
