Here is what I do since I love Chevron Tangs. I buy a baby and in a year I sell it/trade it to a club member usually at a lost to give him a better home when he gets to big for my tank. I have an adult in my 300 but I don't want to chance putting in another just to see if the newbie will survive?
This thought crossed my mind several time. However, I'm not sure we are in an area with enough in the hobby to ensure a new home. I'd love the idea of semi-hand rearing a juvie for new home.
