i am setting a smaller tank up for fryshavon said:Livebearers such as guppies, platys, mollies, and swordtails are best when kept with 2+ females for every male. Livebearers are very prolific and will produce LOTS of fry. You need to be prepared for this. If you are planning on keeping the fry, you need to remove them as soon as they are born so that the adults do not eat them. Some people say that a well planted tank keeps the fry alive but personally this has never worked for me. The fry only make it a couple of days before being eaten. My advise would be to read the Fish Breeding section. There is lots of information on breeding livebearers and others. Good luck and as always have fun with it.
