i am getting a mini-bow 5 tank for christmas and was wondering if platies could live in it. if so, how much and what kind of salt should i add? how many platies can live in a mini-bow 5? r platies crazy breeders like guppies or steady breeders? what should i be aware of so they WILL NOT breed until i'm ready? i once read in a hobbyist magazine that platies will breed in as small as 5 gallons so i am guessing they can live fine in a 5 gal. can there be any other species in the tank? a female betta?
