The turtles shell started getting a little bit of discoloration around the spine, around the bottom edges, and on some of the top right scutes. It does not look like the typical shell rot or soft shell. I thought it might be fungus? or maybe just the natural change since she is growing? or a diet issue? Her diet may seem weird but the sesame seeds and cuddle bone are for calcium and the rest i read is good for extra vitamins. I do take her out whenever the weather is good and let her stay in the sun but lately she has been inside. I haven't seen anything similar to this online yet and i need an opinion on if it is serious or something that she will grow out of. I appreciate any opinions! SOrry for the picture quality, i tried to get the best i could to show the contrast of color in the shell. Once again notice the upper right hand part of the shell and the bottom edges.
