I just recieved my first freshwater stingray today, I ordered him so he was shipped to my house, he is in pretty good shape. . . fat, no dent in his forehead but his belly doesnt look so good, kinda pink and some gray around the edges of his disc. Should I be concerned? Also he seems like he cant sit still on the bottom of the tank, kinda looks like he keeps floating up, any ideas on what is going on.



I'm not sure how to tell though.
