Great advice, friendly people, and lots of frogs!
Dyeing Poison Dart Frog tadpole before front legs emerge Dendrobates tinctorius "Citronella"
That one is obviously going to have a big ,black dot in the middle of his/her back. They are so very cool. From the picture you can get an idea of what it will morph into. With red-eyes you don't know untill they have fully morphed.
You can tell if they're dot or no dot by the time the hind legs are half grown.
