3 spot damsel fish

[lisaFL]

I have a 10g tank:
2 damsels (one devil, one 3 spot domino fish)
My domino fish is starting to loose its black color, its turning a bit white.
Also, its fins are looking a little ripped. I have had them for about a month now.
My water is perfect, had it tested, have a pump, and a protein skimmer.
It can't be the water, i'm not sure what it is. My blue devil damsel is perfect, i'm not sure whats wrong with the domino fish. I'll try to get a pic up of him.
Any ideas?

Not very clear pic, sorry.
He looks worse than he does in that picture.

From the pics in your gallery it lookd like the Blue Devil is the larger of the two thusly it is dominating the Domino hence the tathered fins, etc. also the lightening of the color is a pretty good indicator that the domino is under a lot of stress I would seperate the two fish. the Domino should be fine once removed from the Blue Devil
