Great!

The interest in food is a good thing. Keep sneaking crickets in while he sheds. Even if you can only get one in every couple days it should help. Be sure to calcium/vita D or multivitamin dust on the appropriate days. Have you seem any poop?

I'm glad the spots are fading. It can take a while.

Just keep doing the treatments and monitor. Try to limit your time in his tank to just treatments, feeds, and water changes/paper towel changes to minimize his stress.

Keep up the good work!
