I have a 10g tank right now. There is three female guppies and five baby molly fry. They are 3-4 days old. I am expecting baby guppies any day from all three. I am moving them all into a 29g after they all have the babies and they are about two weeks old. My question... how many guppies can go into the 29g with 5 mollies? I might get Molly babies depending on the genders. I got them from my sister and i am going to swap her so i only have 1-2 males and the rest females. I am going to let the guppies be and do their own thing. How many would you say? I was thinking maybe 30 guppies? Then I would do a mass sell of at least 20 guppies and go down to only 1-3 female mollies. I do just over 50% to 75% water changes every week. Let me know what you think
