You can sex livebearers ( guppies,platys,mollies,swordtails,ect) by looking at their anal fin. If it is a triangle then it is a female if it is stickish its a male.( I dont how else to describe it lol) By the way the third swordtail ( second to last picture) is sick. I have had platies get that weird disease (dont know what it's called) where the belly gets super SUPER thin and the gills nearly or do hang over the sides a little and they die 100% of the time. NEVER buy a fish that looks like that!
By the way im not sure if they are good tankmates but i would recomend a 5-10 gallon tank if you are going to have your betta with them just in case. I have heard that they follow the betta like he's god. LOL
