Thanks so much guys, for your valued experience. I am finding almost everything you mention to be true.
The little guy is EVERYWHERE and an absolute joy to watch. He is in and out of holes, caves, crevices and he traverses the tank all the while. He is always on the move. He does not seem at all interested in bothering any of the corals. (And... now I understand why, when I put my face right up to the front glass, he joined me and stayed there so I could examine him... he is bold!)
The colors are AMAZING on this creature, and his movement, well, I love it. This Neon Dottyback is about an inch long and smaller in girth than a pencil. I will recheck his average in-captivity size. Thus far he has not bothered his brothers and sisters; however, I guess I can look forward (or not) to his active but docile, mind-my-own-business personality to change. It's a joy to catch his racing strip looking body appearing then back into the rockwork and back out in a different place. And he ventures into lower, mid and high in the water column. He is sleek and reminds me of a race car.
It's a VERY interesting and entertaining fish, and... did I mention his COLORS.
Thanks again for the comments!
