here's a breif history of details about alvie. i got him as a baby january 4th. he lives in a 55 gallon breeder tank, with a filter, a heat lamp, and a UVB light. there are plenty of fixtures and fake leaves in the tank for him to play around with and hide in. he's very energetic and twice as adorable. he basks often. i've never really had any problems with him.
Less than a week ago I noticed this little white spot on the back right side of his shell. I don't understand what its from. it hasn't really gotten bigeer but its gotten slightly more defined. i havent noticed any difference in his behavior. i feed him daily with Reptomin pellets and Reptotreat brine shirmp. i give him four pellets and a couple to a few shrimp. I haven't been able to find a definitive guide to feeding so this is what i settled on. he is a voracious eater and finishes the food literally no less than twenty seconds after it enters the tank.
Ive been reading up on what this spot could be and it seems its either shell rot from lack of calcium or vitamin D3, a mineral deposit buildup, or scute shedding. the white spot isn't soft or pussy, its as hard as the rest of the shell. basically the informatiuon i've read says its hard to tell the difference between these things and displayed no pictures. i was wondering if any of you have ever seen a spot like this on your turtle or could give me a better idea of what i'm doing wrong. am i feeding him too much? or do i just need to ad more variety to the diet? what would be the best course of action? please help me, i would die if anythin happened to my little alvie!
here are some more pictures of his shell
any information you could give me would be much appreciated. thank you so much![/img]
