Ich?

Ugh...Im sorry

Can ich develop out of stress? My tank was decease free before my last shipment and now it seems like I will lose everything. Am just tryna see if I may have just received an unhealthy fish.

Well...

Ich itself can manifest from stress, but if your system has Ich and then a stressful situation happens the fish will have to take some of its energy away from its immune system and place it in other places to deal with the stress. This in turn gives the Ich an opening to develop more than it usually would if the fish's immune system was in total working order.

So newly added fish that was dealing with fish aggression(Tangs) could have caused this?

My guess would be whatever you added last (Usually takes around 10-20 days for this to show up unless you are running UV) may have brought it in but no way to know. The last tang could have upset the balance though and caused the stress.

Well it finally happened, lost my first victim. WhiteCheek died this morning. So I guess if this is ich do I just sit back and watch all my fish die? @Humblefish

Have you started peroxide dosing? That's probably your best option for treating ich in a reef. There are also herbal remedies (e.g. Herbtana, Artemiss) that are hit-or-miss. Or there's ozone, oxydator, diatom filter, and other management tools.

Your only other option would be to pull all the fish, and treat in a quarantine tank.

I have been peroxide dosing for over six months but I wasn’t doing the overnight dosing. I started the overnight dosing again a couple nights ago. The Atlantic Blue Tang died this morning but he was soooo covered it didn’t even look like ich. I wonder if it’s velvet?

Look here: The difference between ich & velvet

If that’s the case then I do think this is velvet! It looks even worse in person.

Possibly a mix of ich & velvet on that fish. (It's entirely possible for a fish to have BOTH.)
