I recently got my 10g tank up and running and have 3 Cory's (not sure of sex), 7 Tetras (3 female, 4 male) and 5 Guppies (2 female, 3 male). One female guppy was pregnant when purchased and had her fry in a matter of a few days. It was killed off by the community shortly after. A few days later another female became pregnant and had her fry this morning. I was only able to save 3 of the bunch as I didn't have time to separate before she gave birth. Right now I have the 3 in a breeder box and don't expect them to live but will do my best.
My question is, how often can I expect guppies to be pregnant in this type of a community setup?
