Ich or velvet?

[jasrivas]

I bought a flame angelfish from petco about a week and a half ago and two days ago i noticed white dots all over it. I quickly removed all of my fish from the display and moved them to QT. i am dosing copper power but i have anemone and coral in my display so i need to know how long to leave it empty for so the parasite dies off. is there a faster way to rid it from my display so i can put my fish back?

I also notice scale sticking up on the back of my angelfish's head looks almost like freshwater dropsy. Is that from the copper or is there another issue i need to be concerned about? i could not get my camera to focus enough to see the scale because the fish wont stop moving.

I think that’s ich but I’m not a disease expert.

That looks like Ich to me too, and I think the best treatment is copper in a QT tank.

As far as your DT, you can raise the temp a bit to speed up the lifecycle of the parasite. And, assuming it's Ich and only Ich, then a minimum of 45 days fallow for the DT, though longer is safer.

Here's Jay's post on fallow periods:
