blue tang with lump

[detorka]

Hi im new to the forum so i have no idea what i am doing but ill give it a go.
We had a white spot epidemic go through the tank and started treatment straight away, which i am still doing as i ceased to early and didnt kill it all, however in the first outbreak our blue tang got a lump on his body which looked like something under his skin as it was the same colour blue as his skin. Now the lump has moved to his top black fin but has stayed blue, so he has a blue lump on his black fin.
I spoke to our LLS but he cant identify it so im asking for help here, he also said its probably a parasite to just remove it with tweezers but im not sure about doing that in case i make it worse.
Also we have clowns, an angel, butterfly, lipstick tang, blenny and a ribbon eel in the tank who are all doing fine with no lumps. And the tang is feeding very well and darting around the tank with no problems but he is rubbing on rocks a bit (which can be normal sometimes) and he doesnt have any white spots.
Thanks in advance for the help.

Well, you can probably rule out Brook or Velvet because all the fish would probably be dead by now. You might have Ich. Do you ever see what looks like a fine sugar coating or salt sprinkles on any of your fish? The blue lump is puzzling, as most lumps we see in this hobby are white. How big is the lump? It would be very helpful if you could post pics.

i was under the impression that ich and white spot were the same thing, if so i am treating the tank for white spot, but at the moment none of the fish have white spots (but im still treating for a few days to be on the safe side)
i tried to get a picture of it which didnt turn out the best as she doesnt keep still and my lipstick is an attention seeker and kept getting in the way. but take a look at the pic and see what you think.
thanks

"White spots" is a visible symptom that can describe a lot of diseases in this hobby. Instead of getting all into the details, I've included two links below you may want to read. Now, back to your Regal Tang... I see the blue lump on his black dorsal fin and honestly, I have no idea what that could be. I guess it's possible that it's some kind of tumor protruding through his skin. The pic is kinda blurry. Does it look like an external growth or something internal that's protruding through his skin?

ok we got a better picture, it protudes out of the skin, could it be a tumor? how do you treat them, i hope some one can identify this and help us as she is a beautiful character in the tank and has a huge personality.

Honestly, if it's internal and/or a tumor there's really not much you can do. I wouldn't try to do surgery or remove it with tweezers as your LFS suggested. For now, just be patient and see what happens with it. It doesn't look that big anyway. There's a chance it may not get any bigger or become a problem for your Tang down the road.
