how often do endler's livebearer reproduce?

Endlers are about the same as other livebearers, 21-28 days depending on tank temperature and water quality. The cooler the tank, the longer the gestation. I keep my endlers at about 78F. Allegedly, the warmer the temp the more likely you are to get male fry.

They aren't quite as prolific as Guppies though and have smaller batches of fry. They also won't eat their own fry, the chase them a little, but don't eat them.

They reproduce just like guppies and any other livebearer, so a gestation period of about a month, more or less. 21 days is pretty quick, however. After a couple batches of babies, you won't really be picky about when they give birth. I think I have like nine generations of guppies in some of my tanks, and they just never stop having babies.

And anyways, endlers are very closely related to guppies (I think they're just a different kind of guppy), so whatever your guppies need, endlers will appreciate.

They reproduce similar to mollies and guppies. So about every 20-30 days.
