I took my serras hide out a few weeks ago to net him out. I decided later not to give him up, and kept him. Now he's all over the tank, showing better colors than ever before, and he's a lot less shy than he was. He still bolts to the other side of the tank if I get really close to him, but I think that has more to do with him being uncomfortable in his new environment. He used to just sit under a piece of deco all day, but now he swims up and down the tank through the air bubbles coming out the line across the back of the tank. It's funny too. my tank has a mirror background and he shoals with 3 other images of himself in the corner... 
If you have a well established serra tank, take the thing he hides in out. It's amazing.
I took some pics, and even figured out how to shoot short videos with my cam, but I can't find the USB cable. I think I may have already packed it up. His colors are amazing right now. He's starting to look more like an adult. He's got tiger stripes right now instead of spots. His humeral spot is dark as ink, and you can only see it an angle. From a complete profile shot it looks like silver with a little dust on it. He's blinging like a diamond on the dorsal aspect. Bright orange gill plate, but his tail fin, anal fin, and head are all getting dark as hell like a rhom.
That's it....I'm keeping him... F*** 'em.
