What the heck happened to my trigger?

thanks for the encouragement michika! It does sound like an infection more and more now. Is there a particular type of antibiotic that would be best for treating it? I'm crossing my fingers and hoping that it's still ok when we get home and we can start treating it. I will keep trying with the clams and nori like you suggested and add an airstone and see how it goes. Also, the fish is currently being housed in our salt water mixing tank, which is a 75 gallon tank but is only about half full right now. I have an empty 10 gallon that I could quickly set up, would that be horribly small for it? I don't really want to contaminate that tank if I don't have too.
