i have a concern about one of my res - the spaces between his scutes seems to be growing larger as of late, is this indicative of a problem? overfeeding? lack of something in his diet? other?
some pics:


perhaps this is normal, perhaps this me overthinking, but his tankmate isn't exhibiting this type of growth, so i thought i'd pose the question. the turtle is approximately one year old, he gets 4-5 reptomin pellets once a day, and has uva and uvb lighting 14 hours a day.
thanks in advance.
