The Achilles tang is my favorite fish, I have had my current one for a little over 5 years now, as far finicky eaters go, I believe mcoomer nailed it, they are a little harder to get to eat at first, but now mine will take flakes right from my fingers. I always get live brine shrimp or live baby brine, no fish I've come across can resist them, it absolutely needs nori tho, & if possible let it pick at some all day. Like all Tangs it likes to swim & also has a temper, not the most agressive surgeon fish nor the least. I would say it should be your first tang if you plan to keep several types. Just remember if you decide to get one, they will require your attention for a while, especially in QT, once established though, they are no different than any other fish in our tanks, except for their AWESOMENESS! You can see mine on the right side of my avatar, right above the Hippo.
