They were always visible but not as visible around the 23rd ish, looked like it was almost gone and now becoming more visible again today. Flaring up. No flicking, no head shakes, no erratic swimming during this period. And incredible appetite

Hmmm.. they almost look like warts! Accidentally drop a toad in the tank? lol I'm pretty stumped. We'll have to rely on @Humblefish for the answer here. I'll take out my notebook and take notes ;)
 
It's very strange! They were really noticeable for about 3-4 days (started around the 15/16th). After a few days she looked good and now they look to be more pronounced again. Originally, Some of the lumps looked different sizes. Thanks for your ideas. Hopefully @Humblefish has some ideas as well.
 
I've seen this before with Hippo Tangs and after a little digging, there usually is a logical explanation:
  1. Was this fish exposed to copper recently; say within the last few months? I've seen cases where tangs will develop "pimples" sometimes following copper exposure.
  2. See where the fish sleeps at night. Is it within range of a stinging LPS coral or a nem brushing up against it?
  3. Lymphocystis or a bacterial infection are sometimes to blame. Sometimes its an internal infection just below the skin, protruding outward.
 
1- no copper recently. She's been in our DT since July 2015.

2- she sleeps hidden in the rock work that she's near in the picture. I'll try to get a better one today. I don't think anything can reach her where she is but I could be wrong. A bristle starfish hides out near her area sometimes.

Green Brittle Starfish by any chance? Those will try to take down whatever they can, including fish.
 
Not a green starfish. We have a serpent starfish and a brown brittle star. Both are reef safe from the research we've done and what we were told.
 
This is where she sleeps

You can see her tail in the last pic. She hides in a cave up high in the rocks. Where she's noticeable in the second picture is how she swims in and out of her spot. You can't see her when she's really in there so I'm not really sure corals can reach her to sting her.
 
Thank you for info. I dosed tank with prazipro. Here's a picture of my hippo tang. She has these lumps on her for appx two weeks. I thought it was ich but no scratching, normal breathing and eats nonstop. Could this be related to naso.

And naso still does not show these bumps and looks normal other than the non eating issue.

It looks like Ich to me. Have you ever gone through ich infestation in your tank before or added any CUC or corals recently?
Did you check your water parameters lately? Some people choose to go fallow for close to 3 months to eradicate Ich, some just deal with it and let the fish build their own immune system. Problem with the second choice is that they will be vulnerable to parasites once water parameters swings considerably or under extreme stress.
 
Parameters are "on point" per my husband. We have an apex system set up so everything is monitored closely.
We have added corals recently from a new place that my husbands buddy works at on the side. We don't have a QT for corals though. My husband just did a coral dip on them.
 
We have had ich before and treated with kick ich, raised the temp on the tank etc. That was August/September time. Haven't had any issues since. All new fish go in a QT tank for a few months to be monitored.

Kick-Ich will not eradicate ich. It may manage symptoms for awhile. Bottom line, ich is still in your tank.
 
Unfortunately, we are leaving for vacation on Friday and have someone looking after our tank. We can pull them all out when we get back and really get rid of it. Is that what you think the hippo has?

Could be, although the spots being in the same place for two weeks doesn't line up with ich's known life cycle. I would reevaluate once you get back from vacation.
 
If it is ich, is it normal it would only infect one fish? There are no spots on any other fish. (2 wrasses, 3 gobies, 3 tangs including the hippo, 2 clowns)
Thanks for all your help, it's greatly appreciated!!

That is possible, simply because that one fish's immune system is the weakest. Though I'm thinking that this isn't ick. That doesn't mean that ick isn't still in your tank, just that I dont think this is it.
 
Ok good to know. Is there something you would recommend to give her immune system a nice boost for while we're away or should I leave everything as is?

You can get a vitamin supplement like Selcon or the like and add it to the food. That will give all the fish's immune systems a boost.
