I just saw your pictures-beautiful colouring! I have one of my froglets that likes to bounce back and forth from Yoki's colouring to a beautiful green. I also have a couple of froglets that are golden bronze in colour.
Yoki is about 2" long...and 2" wide too!! He was about an inch when I got him, so he has plumped up nicely. The picture I included below is of my female, Taiki. She was smaller than an inch when I was gifted with her and she is now almost as big as Yoki. I also have 5 froglets all around 1" long that I have not positively sexed yet.
