When I got him 3 years ago he was 3" and has grown to 10" in my 150 reef. He is my favorite fish, tame(will roll over so I can pet him), will eat from my hand and is beautiful. I paid 75.00 for him and will sell for the same only if he goes into a tank at least 300 gal. It will hurt to let him go but want him to have more room to grow and swim. I know that some of you have larger tanks and would be a great addition to any large tank.
