It "oozes fluid"? That doesn't sound good, at all. That sounds pretty unusual.
The "dent" will most likely clear up after the snake sheds a couple times.

I hope you're not keeping the snakes together still.
A ringneck, will gladly eat another ringneck, especially if it smells like a prey item in the enclosure.
