Here is one of the 2 frogs and is the main reason I had been looking for advice. Tho he seems to be eatting and acting normally, from what I can tell, his coloring has concerned me for some time. Also his next sac has seemed swollen to me, however, form all I have read this is normal in mature male frogs, especially if they are vocal. Which they are lol I am thinking that once we upgrade their habitat they will be much happier.
