My husband has been wanting a purple tang, and I got a good price on one. So I bought a small purple tang and a new small yellow tang to introduce at the same time, so's to reduce the chance of aggression. Which means I need to find a new home for the yellow tang currently in my tank (I don't want to stress him or the new fish out too much). He's about 3 years old and about 2.5 inches tall from top to bottom (maybe a little more, it's really hard to estimate). PM if interested.
