So sorry for your loss

lots of things can have been gone wrong here. Is the frog in your avatar the one you lost?
would you have pics of your frog?
Would you please answer questions of the trouble in the enclosure. This way we can over and see if there were any problems to avoid in the future.
What you describe is not really typical, it might have been excessive shedding, either way lets try to figure that out.

And to answer to your question, yes they love company of their own.
