one of my frogs, when i got him, he had this red dot on his back and he was slightly paler than the rest. hes my only male so i just said "must be what male frogs are like". but over a week he has gotten paler and the red dot has turned into a red stripe all along his back. and he didnt eat at all. just today i had to force-feed him using a guitar pick and a cricket. was that the right idea?
