chameleon blenny?

Ive noticed recently that when Zeus my bi-coloured blenny wakes up in the morning he has small discoulorations, the corners of his lips are white and his horns (?) have changed from purple to white too.
This has happened for quite some time now. Only just recently when i catch him sunbaking on a large flat peice of live rock the discolourations are there, along with faint white spots along the length of his body. But when he notices me and swims around a bit they dissapear...strange

I guess my question is, is this normal? should i be worried? Is this ability unique and Zues is in fact some sort of.. say...super-fish?

Thanks in advance.

 

That sounds normal. All tangs I have had go lighter at night and while at rest. I have one in QT now that is staying light...


As long as it is eating and acting normally, lightening of colors are usually normal!

 

My bicolour Blenny does the same thing. Its normal
My flasher wrasse also goes really light

my sailfin blenny does that 2, he looks nice at night.

 

My lawn mower blennie changes shading depending whether he's sitting on a rock or the gravel.

 

ah thanks all, i feel a lot less worried now. He is the cutest fish too, i get into many a staring competition with him =)

 

I have yet to find a fish that doesn't do that
