If you have some kind of clippers, large ones, maybe a gardening tool? You can cut away whats dead or dying hopefully. Thats the only way you might be able to save what isnt infected. I suspect you will have to really chomp the skeleton hard as its pretty tough to cut through. Maybe if you have some kind of dremel or something similar that might work as well.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
