Are endlers and feeder guppies related?

feeder guppies are just regular guppies or they could be gambusia, and you're right. Endlers livebearers are actually a type of guppy, although widely speculated whether or not they're actually a guppy but rather something completely different although related. They do however fit all the characteristics of a guppy.
 
it all depends on the meaning by "the same". they are a completely different species just like a swordtail versus a platy. They are the same in that they are closely related livebearers but endlers males only reach half the size of a guppy and using them as feeders wouldn't be as cost effective so I don't see why they are being used other than they multiply as fast or faster than guppies. Unlike guppies, endlers won't eat their young so more survive. Kyle
