Dumpy tree frog? What am I doing wrong?

[Mr Leopard]

If you haven't already, I encourage you to get back to the seller to let her know that she had misidentified the frogs and that the care she was giving them was not appropriate for this species. That might avoid similar situations in the future.

I'm also guessing that these frogs were wild-caught. If you feel up to it, and you think she's actually doing this to make a profit, I encourage you to let her know that engaging in the trade of wild-caught animals is wrong. It might even be illegal for her to sell that specific species where she lives.
