These are mixed endlers. I would list them as black bar endlers but I do not believe that they are true black bar endlers. They are super easy to breed and I have them in a tank with almost no cover and yet there are new fry growing up every day! You will get one male female pair.
These are bright orange swordtails. Swordtails do tend to heat their fry so if you are intending to spawn them make sure they have a lot of cover or that you pull the fry. At this size they will be unsexed. They will be anywhere from .25 inches to 1 inch. I have 4 generations in the same tank right now.
