HELP! Are my fish sick?

[boyohboy2]

HELP.... need some help on the pics... do my fish look like having diease? marine ich?

INFO:
--- I have a 50G tank +30g sump. I just recently bought 3 chromis. They looked all healthy and acclimated to the tank nicely and all 3 were swimming around happily and ate food right away. I did NOT quaranteen them unforturnately. ---
--- I actually have a separate possibly QT-tank already with SW in them with a powerhead and lotssss of cheato there next to my balcony for the sunlight... but for some reason after I got the fish and I did a quick test, the nitrate in the QT tank was like 40ppm or something, so I decided to put the 3 chromis right in the display tank.
-- 2-1/2 days later 1 of the chromis died, of no apparent reason. I have a pistol shrimp, 2 cleaner shrimps, percular clown, coral beauty angel, PJ cardinal in my tank.
-- so this is now after another 4-5 days and I'm still worrying about diease from the chromis (why the death?!?) so I stared at my other fish for a long time and took these pics. The 2 remaining chromis are still looking fine and eating as of tonite, I don't see anything wrong on the chromis, not yet anyway touch wood.

But these below worry me: (click on the link for full size pics)

Coral beauty-- 1 bigger whitish dot on the top fin. 2-3 small white dots near the head... but the small ones seem to have disappear late tonite.

Clown#1 -- few black dots. Checkign my old pics from a few weeks back, the clown didn't have these black dots before...

Clown#2-- couple of black dots... and 2 white dots near the top fin (the shade of orange color was only coz my camera flash was above water level, nothing wrong there)

Do I have a problem here? ich and black ich? :eek2: :eek2: :eek2:

Also another thing to add... my pistol shrimp is digging alot so he's often stirring up quit abit of dirt up in the water... which u can see in the pics... and **MAYBE** some/all of the white dots on the fish are simply dirty sticking on them?!?

Ok was just talking to my gf about the fish

She said she's very sure my clownfish had those black spots before somewhat recently. As I said I couldn't see them in my old pics but those pics were from more than a few weeks ago.

So I duno... hopefully the black dots isn't anything but just some pattern/scare?! and the white dots are just dirt kicking around in the water?!

The circumstantial "evidences" do worry me still tho ... ie 3 new chromis and 1 dead...

sometimes the black spots are cuased by the anemone- sometimes its actually black ich.

I had a yellow tang in my tank get black ich (no anemone) and my clowns didnt contract it (yet)

Your coral beauty definately looks like hes getting ich and needs treatment.

Sorry to say but it definitly looks like ich to me. That is exactly what my clown looked like and then he got a few more spots and a couple more. When he had about 10 spots on him thats when I put him in my QT.
