red-leg syndrome?

[eaya]

sad to say that i discovered one of my frogs this morning dead. I noticed a few days ago that his hind legs and stomach had a pinkish tint to them, but i didnt really think anything of it, since he appeared to be eating and didnt seem lethargic. Last night though when I came home, he was VERY red. I would imagine this is red-leg syndrome. its difficult to confirm this though -- couldnt find too many pictures online to compare this to. So, below are two pictures of him after I found him this morning. The top of his body also had dark splotches that I noticed too -- not sure if this is some sort of early stage of decomposition or if this was part of his illness.
