Also maybe pink/beige describes it. He has similar coloring on his arms. It kind of matches the skin on his belly.
Activity wise he is doing fine and eating normally. No lethargy and lots of swimming.
But I will still post pictures.

My other frog was looking a little bloated so they are in separate hospital bowls.
I am using maycin 2 and a dash of salt.
However I wonder if she is not bloated, but growing? Everything seemed symmetrical. I still am going with treatment.

Also has anyone tried lymnozine? I don't know if pet stores carry it, but it's similar to koizyme?
