Overfeeding?

[powerstare]

I'm new to this new forum but I figured it would be useful to find answers from people who are knowledgable about feeding toads and frogs. So I just came from work a week ago (45 minute commute), and I rescued a baby toad (about 3/4 inch in size) who was found in the passenger area in the back of my car. I'm not sure how long it was there for, but I've been keeping it a 5 gallon plastic container with a water dish, hiding spots, and coconut fiber as my substrate. I've been feeding it pinhead crickets and very small mealworms I've bought at the pet store once a day (just giving the toad 1 mealworm/1 cricket a day). Its been eating which is a good thing, but I plan to slow down since its gotten to a pretty chubby size since I found it. Just hope its not impacted or anything serious. I've been researching that such foods contain chitin, which is hard to digest. Just looking for advice and if anyone can inform me the species of the toad, it would be appreciated! Attached is the current state of the toad.

Thank you,
