I have a maroon clown, yellow tang, and a unicorn tang along with two cleaner shrimp, three peppermint shrimp, snails, hermits starfish, anemone. It's a 90 gal tank with sump. My question is I'm going on vacation and not sure how to make sure everyone gets fed. I feed them the food that the tropicorium guys make so it's frozen. Is there a safe dry food that I can put in an automated feeder while I'm gone? I was told that most of the dried stuff has copper in it and is not good for inverts. any suggestions of what I should do for food and auto feeder?

Thanks!
