I was gone for over a week to get married and had someone come in every other day to feed and check things. Do you have anyone at all that can come in, maybe just once in the middle of the time you'll be gone? Me personally, I wouldnt leave the fish for that long without food.

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