Even though they aren’t quite babies anymore, these juvenile male Orchid Endler’s Livebearers are just beginning to show their coloration. At a mere 7 weeks old, they’re already able to create the next generation of fry. However, in this tank, they’ll have to cool their hormones! The individual who purchased these fry made sure to request males only to avoid a population explosion. And, they were nice enough to share some images of the young boys in their new home:
As you can see, each of these guys has the beginning of a sword on his tail fin, and the dark spot of black is beginning to show itself there, too. Even before these guys were so easily identifiable with their colors, their gonopodium was a clear give-away of their sex.
Good luck in your new fraternity tank, boys!
