Radiant wrasse turning very pale????? Doesn't seem normal

[fishoholic]

I know most wrasses change colour from juvi's to adults but mine got very pale over night. For the past 2 months he's been getting a little bit whiter on the very top of him, and a bit lighter on the bottom, but today I got home and he's very pale seems healthy still so I'm wondering if it's just the change of colouring or if I should be concerned. Google images show they get a tiny bit paler but not as much as mine is now.

He is about 2-3 inches in size and is in a too small tank, a 34g cube. He was in Doug's 260g, but because of his small size when we got him, the leopard wrasse kept chasing him and attacking him. We plan on putting him back into the 260g (when he got big enough) but I'm wondering if the small tank is affecting him Any thoughts????? Doing a water change tonight just to be on the safe side, but all the other fish seem fine and normal.

Here is a pic of him as a juvi


Here's a pic of one (off the internet) that I'm pretty sure is an adult


This pic (off internet) is similar to what he looked like yesterday


Here's what mines looks like today (wasn't any where near that pale yesterday)
