Red scooter dragonet

Just wondering if it looks thin or fat and healthy, I picked it up from the lfs for 80 dollars and as soon as it got in the tank its eating pods :) but it wont last for ever imo, I tried feeding it frozen mysis/brine to no avail even though I asked the lfs to feed it some before I bought and it ate it, but earlier I saw it eat a piece off a rock so fingers crossed, could it just be settling in and will eat more in a few days ?, but yeah just wondering how it looks cheers :).
