Help me Identify Please

[Shaunbeds]

Hey there guys, I am new to Marine and have just bought my first tank and set up. With it came 4 fish, 3 of which I have identified, the 4th I am having no luck with and cant find it online anywhere.

I thought it was a Rusty Dwarf Angel fish, but my local aquarium centre says not although even they could not put a name to the little fellow.

So I am posting this hoping someone can help me put a name to the guy, he is VERY shy and darts all over the place, often hiding in the caves etc.

If your interested in seeing more about my aquarium I have set it up on Aquatic Log at this link... shaunmook's The First Marine
Thanks Shaun

Def an angel....May be a nox or midnight ....

 

[Shaunbeds]

Its always been that colour which is pretty non descript and plain!

Looks like a centropyge Sp, maybe a c. vroliki or a c. fisheri? Really hard to tell from the color of the picture you have.
