Well then again, a person can buy a fish without knowing how it is going to act down the line. I myself bought a baby Regal Tang once. I was able to keep it for more than a year. It then started to look nervous, which I find a lot of tangs do. I then took it back to the LFS where I originally bought it. They put it into their 1500 gallon show tank where it looked a lot less nervous. So in the end I feel this
was kinder to the fish than keeping it.
