Your thoughts.

I would say Yellow Tangs are somewhat easy to keep, providing that you keep them well fed and give them plenty of space to swim. I feed mine about three times a day and he is really a fat little sucker. I really hate seeing these guys under fed. They are really should be like fat little pigs.

Ditto on the space things. My Sailfin outgrew the 55 gal tank I originally had, and his behavior definitely changed. Would pace up and down the glass, make threatening moves towards me when I came near the glass. Then I got a 90 gal, and he was all better for a while. That was 2 years ago. Now he's starting to pace the glass again, running his nose up and down the front side... Hey honey, I think we need a bigger tank!
(if only it were that easy)

I agree with everything that has been said especially on the size of the tank.
Make sure you choose a healty one. It should be plump, not thinning, clear eyes, no spots or tears on it body. If not pass.
Give it the garlic treatment as a preventative against ich.

I would like your thoughts on keeping a yellow tang. What it needs to thrive, and how they like their living conditions.

Hi, they tend to need a lot of space. I would not keep one in a tank under 75 gallons. of course the shape also matters. I would say they prefer a long tank so they can swim back and forth. This is especially true for keeping more than one. Also, they need a supply of macro algae to graze on. You can try dried nori or culerpa. good luck, Rich
