Whats wrong with him?

I am acutally quite suprised I am posting in this category "Disease and Treatment." My tank parameters are all good and my salinity is good. I do water changes about 1 every 10-12 days. But my Fiji Blue Devil Damsel has been acting weird lately. My niger, Yellowtang, and snowflake eel are all fine. There is no sign of disease with them but my damsel has dulled in coloring and is always making shimmering movements. He doesn't scrape himself on the rocks nor the sand but makes jittering, shaking movements like something is bothering him. He is also hiding more and is not swimming around the whole tank like he use too. He is not being picked on. All my fish get along perfectly so he's not stressed. I don't know why out of all fish my damsel is sick? Will this eventually just go away?

Maybe you could post your exact water parameters for me so that we can confirm that is definitely not the issue. I am talking about pH, kH, ammonia, nitrite, nitrate, salinity, and temperature.
How long have you had the fish?
When you look closer, can you notice anything on him ever?
What size tank is this?

92ProTruck: Well if it was stray voltage, don't you think it would be affecting my other fish too. I mean my damsel should be my most hardy fish that I have.
Beth: All my fish get along and no one gets chased or beat up.
lion_crazz: Nitrates- 0
Nitrites-0
Ammonia-0
pH-8.0
Salinity-1.022
Temperature- 78 degrees
Phosphates-0.1
kH- I don't have a test kit for that but I am sure its fine since I have
Karib Sea Sand and I use additives in my tank every other day
to balance that out.
I have had the damsel and yellow tang for about 6 weeks, my niger 3 months and snowflake about 2 months. Its a 75 gallon tank and when I look closer the damsel looks duller in color, like he is losing his yellow and getting is getting a duller blue. But today he looked a little better but I am not calling it safe and I still want to know what caused this to prevent this in the future.

I am feeding them 4 different kinds of foods.
1.) Prime Reef Flakes
2.) Spirulina Tetra Flakes
3.) Algae sheets
4.) Nutrafin
I mostly feed them the top three. I switch it up

I'm no expert...I only mention the stray voltage because your description of your fish matches perfect to what my 6 line does when someone unplugs my grounding probe. He is first to feel the effects, which is immediately. The other fish so signs a few weeks later. His behavior is as you descibe and his skin dulls. The chances you have stray voltage are maybe slim to none...but it only takes about 10 seconds to check.

with a multimeter/voltage meter, set it to AC volts and put one lead in the water (don't touch anything like the tank or canopy) and one lead to ground (stick it in the round ground hole in the AC outlet if you know the outlet is properly grounded). Read voltage.
