LOL! Endlers do look like feeder guppies! Yeah, a co-worker was looking to unload a bunch and I was a likely victim. I got them, along with fishfood, a net, and a fluorescent light, for some CP's. Supposedly these are Endlers, but they might have been the result of some crossing with real guppies. But from what I've read by googling, Endlers and Guppies can mate but don't produce viable offspring. So for all I know and can see from above, these may or may not be what they are purported to be. They sure do propogate like guppies!
