I have two male cobra endlers that were meant to be fed to my Congo. Well, my kids "saved" them and they are now in a tank with some female feeder guppies. They are relentlessly trying to mate with the guppies, even the pregnant one. I love watching these two guys! They do this crazy little mating dance for the guppies. They spread their tails as wide as they will spread, arch their bodies into an "s" and vibrate. It is so interesting to watch. I think I'm gonna dedicate another tank to them and breed them with guppies for feeders. I know the offspring is known to be infertile which is great because that will keep the population "somewhat" under control. So, has anyone here bred endlers and guppies? Any pics of the offspring?
