How big will the tank be? If it'll be big, you could get a ratio of 1 male to 3 females, and have tons of fry. if nothing else, the fry will feed their parents.
I don't think the original post was for feeders because I thought the same thing. Plus, it's safer to go with tank-bred fish because they are more forgiving of mistakes and less than perfect atnk conditions.
well i didnt actually mean 10. i meant along the lines of 5. i usually hold guppies in my community tank and feed them to my cichlids. (sorry i have been trying to get them on flakes but this was all they ate at my lfs). i noticed some pregnant females and i moved them into my fry tank with my month old mollies. they are around the same size and i was also wondering if my mollies would eat their fry. they are maybe tops a centimeter. how big would the fry be if the guppies did however drop? thanks
