Here is a picture of him

While that looks like a spinal injury, it may not be that, especially with no apparent damage to its snout. When I see a new yellow coris bent like that, but still trying to take food, I feel that it is pretty safe to conclude that it is UNWD:

Sorry, but this has no known treatment and is usually fatal.
