Blue Atlantic Tang
Tangs need a lot of space, and this juvenile Blue Atlantic Tang - Acanthurus coeruleus - never was very happy in my 55g reef. Although very healthy, and very fat, it could race across the tank in the blink of an eye, literally! Its discontent resulted in it bullying other fish, and so I let it go to another reefer. It loved Nori and Romaine Lettuce, due to their vegetarian diet, but it enjoyed all kinds of meaty frozen foods as well. Feeding twice daily ensured its good health. Expect lots of fish poo.
