fire belly skin problem

[Bombina Bob]

Hi there
Ive never seen this sort of problem before but fire belly toads normally can have color change from olive brown to very light green. i would advise against feeding mealworms though because of their hard exoskelleton and that they can bite the toad. i would try earthworms, they are the highest in nutrients and can grow freely in a compost bucket with soil or in your backyard. If the toad dosent get better by then i would go to a vet, in the phonebooks the vet would be under EXOTIC.

I really hope your toad gets better!
