I bought 5 guppies today, 2 male, 3 female for my 85 litre aquarium, which has mainly platies in it at the moment. There is one male and one female that have particularly nice colourings that i would like to make sure "do the deed" together as i think they would have amazing fry. I have a fry tank set up, if i put the one female and male in it together, will they mate? Or will i need more than one female in there with them to encourage it? I know guppies will pretty much do it themselves with little or no encouragement from me, but i want to make sure these two make babies. Any suggestions?
