Need information on care for platy
I just added a female red platy to my 10 gal unfiltered heated tank with my betta. I decided to get the platy at the store after reading some threads indicating that one platy was fine by itself, but after getting home and doing more research to see if I should set up the filter that I have (which I can't today, because surprise - I don't have a sponge and need to buy one), I keep finding conflicting information both on this site and on other sites as to whether platys need to be in groups and whether or not they need a filter. Could somebody please lay out a comprehensive list of guidelines for caring for a platy/platys? Thanks!
