Frogfish experience

[Animal Mother]

I got a tiny Frogfish a couple of weeks ago and he isn't growing much and doesn't really eat as much as the others I've cared for. I'm starting to think he is a "Pygmy" Frogfish. He is only about 1.5 inches, and I can't really see his lure since he's so tiny.

Does anyone have any experience and/or pictures of any of the Antennatus Frogs? Any links would be great.
