Very cute little guy you have! What pyramiding means is that his shell is a bit bumpy due to dry conditions (from his previous owner). You can help him grow smoother new growth on his shell with humidity. Which sounds like you're already working on that so good job.Hi could you tell me more about what u mean by he is pyramded we have only had him since last Sunday his temps and humidity are as recomended as are his substrate and food what could I do to stop it and how do you know he has is obviously it must be noticeable but I don't know what I'm looking for thanks
