, Right away I noticed three things, Eye sunken, forehead sunken (not from eating issue (looks very different) and also the lip is a touch bat, meaning overall its a number of development / birth defects.
Honestly if it's eating and doing ok, let it be and let it grow and see what happens, its a bit more of a risky ray to own and grow out but hey its a good looking ray and hopefully it does really well. Just never know when taking a risk on a ray in that sorta shape. Treating issues that are not there is, well pointless at this point. Wait and see if something actually shows from poop or lack of eating or skin issues and then treat as needed.
