Hi there. Now im one for getting really worried over tiny things concerning my tortoise, being a new owner of my hermanns Voldetort (3 y/o) but ive noticed his shell appears to be slightly ridged and the pastron almost appears to have a very slight concave area on the largest section near the middle i'm unsure whether it is as a result from my care or if it has been from before as hes always had a slightly bumpy shell and i only got them last october at 2 years old. Do you think this looks like early pyramiding and if so, any advice on what to do to prevent it progressing further?
