I have them in a 10 gallin aquarium with a heater and will be adding a sponge filter. Mine is bare bottomed right now but im considering sand or rocks. Not sure yet. Just add adult males and females and keep temps around 70-80 and they will breed(very profolic breeders i might add) either i will add plants and lots of hidey spots for the fry(baby fish) to hide in or ill set up another guppy tank to put the fry in. Not sure which im gonna do yet lol. But there very easy to breed
