do blue tangs have a characteristic that looks like a fungus that grows on their heads?

Blue tangs do not have any such growth.  However, young unicorn tangs can look much like blue tangs so the aquarium may have mislabeled the fish.  As the unicorn tang grows, a protuberance appears and grows above its eyes.  In the early stages of this growth, the protuberance may look like fungal growth.  The link below has a picture of a unicorn fish with an extensive protuberance.  If the growth was anywhere other than directly above the eyes, as in the linked picture, then it was a parasite which may victimize tangs to the exclusion of other fish.  Many species and genuses of tropical fish have parasites that infect them and them alone - tangs are not known to be particularly parasite prone and are considered to be fairly hardy aquarium fish.

Fungi such as that causing athlete's foot (Tinea pedis), flourish in an evironment such as feet.  The foot has 2 characteristics fungi grow well in.  1. Dead skin and 2. a warm moist environment.  Some people are more prone to fungi foot infections do to their immune system.  Many of the over the counter medications work well but if it moves into toenails, it is more difficult to treat.  Prescription meds such as Lamisil are needed for this and need to be taken for 4-6 months in total to cure.

I'm not for sure but I think it is the way that it grows or maybe the fine little hairs that grow on them. This site might help you more than I could.

if its called a fish of any kind it has gills

It sounds like a pterigium or a pingueculum but without a visual, it is impossible to diagnose. See your local Ophthalmologist.

Many mushrooms can be identified one from another based on some often dramatic color changes that will take place once picked, handled, and of course, dried. The tendency of many species to oxidize merely by handling them is often so dramatic (white to wine red to blue, dark purple almost black...all in one species alone over the course of an half-hour perhaps) that one is surprised at the amount of color change despite it not having  been treated with an actual reagent. Anyhow, why I'm telling you this is that to me at least, this characteristic suggests that many mushrooms upon drying may well undergo chemical changes significant enough to affect the taste. As you point out, there are any number of fungi that are known to be better after drying. Morels (Morchella sps.) are a good example of a commonly eaten fungus where this applies. Or, on the other hand, many must be used while still fresh or else will lose their flavour. Here, truffles (Tuber, other genera) being a notable fungus where freshness is a must. White Matsutake (Tricholoma magnivelare) mushrooms picked here in the Pacific Northwest are all destined for Japanese markets, and they must be there within 72 hours, right from their picking in the forests of BC to the shelves in Japan. Again, freshness is a  must, or at least if they want to still have any decent retail value left once there. \nOf course there may be just the simple matter of the fact that while an Agaricus (store mushroom) dries, it is still producing millions of spores. Agaricus spores are all deep, dark chocolate brown. Meadow Mushrooms(Agaricus campestris) are a close relative of the supermarket button mushroom. They both have pink gills when still young, but the older it gets, the darker brown the gills get as they are covered over with millions of spores. These spores will stay attached to the dried gills where they were produced. Once dried, the spore covered gills will shatter very easily (gills are very, very thin). Once this is all thrown into a watery broth, it's likely you will get much of the color your describing here. In fact, try it with a pale or white-spored species of mushroom sometime and see if the color remains pale.  If so, you've got it. If not, my first idea is about the best I can possibly even conceive of (and, as an accredited mycophile, I know mushrooms very, very well <g>)

It's not typical, but I suppose it could happen. If you've always had it and it hasn't grown or changed color you should be okay. Check with the doc if you're concerned.

Spore bearing would be acceptable in this case.  Also, moss is not a fungus.

I believe (though not sure) what you are referring to is the Mongolian Spot, visible at the base of many asians spines.  Sometimes this disapears as you grow older.  Personally I find it quite attractive, so I wouldn't remove it if I were in your shoes.

They are arachnids, not crustaceans. Easy to find on the Indian Ocean shores. Dead animals eaters. Breath using gills, two sexed animals, egg layers, free swimmers. Outstanding feature: their blood is used as a reactive in a positive detection of human encephalitis.\n\nmore info: Barnes book of invertebrates

fungis...he should go to a dr...it could be bad!

Fungi are chemoautotrophs, so they don't hunt for anything. \nBut I'd hunt for them, oyster mushrooms are delicious!

I don't think there is such a structure.  The basidia which bear the basidiospores are found on the gill surfaces.  I think the only thing separating them is space.

I have always been partial to a fungus that infects ants.  When this particular fungi reaches reproductive maturity, it sends a fairly large fruiting body out of the ant's thorax.

my favorite color is blue...i've always liked it and it looks good with my skintone.  my favorite plant?? probably a cactus because it takes me quite awhile to effectively kill it.
