Very top is an orange spot filefish. Coralivore. Only eats sps, with time and the right fish, you can train it to eat frozen, but it's hard to find the right fish and takes a lot of effort and clean water to get to eating. I dumped ridiculous amounts of food in my 12g nano to get that little guy to eat something. He finally stuck with mysis and nipped on my sps API was happy. Had him over a year then decided to move him to my 65. I think he was too slow and too small to compete for food and fight the flow, which I'm assuming flow was an issue due to the lack of nutrition he was receiving. I miss that little dude. When my big tank is matured with sps colonies, ill try again with a pair this time.
