how do you get rid of white fungus

I have a small colony of zoas (tri colors) that have about 50 polyps on the rock. The entire rock has a whitish clear fungus around the base of the zoas. Now they dont show any signs of stress but ive taken the precaution to separate them from other colonies. Is there a dip I can use to rid the rock of the fungus with out hurting the zoas?

ill try and get a pic if necessary but its self explanitory-

Cut away the diseased portion, dip the rest in Lugol's solution.

What causes the white fungus to develop? I notice that sometimes after fragging a large rock of zoanthids, the fungus develops and takes out some polyps. There a way to prevent the fungus?

Mucho's Dip isnt a cure all end all of zoanthid problems, but it can most certainly help. You do want to remove the dead polyps, as they can sometimes spread.

Alot of times,zoos are closed and look white.Dont panic,unless it lasts for days. From the pics I would suspect light intensity and water quality. Raise the rock off the sand to mid tank.

Craab, could you explain your dip. I have got this fungus too and my zoas are melting away. I have tryed the lugol's dip and they fall apart faster. And it seems to just keep spreading. I take any sick looking out and put them in quaritane but alittle later another breaks out with it. I did a water change and that didn't cure I'm sure it helped the tank overall. I could use some real help!

its had the white stuff for over 8 months and i havent lost any polyps ( i dont think) but then again i have gained any either. i doubt its the water quality because i have much harder corals that thrive with no signs of any stress. Im gonna try an dip and place them alittle higher in the tank and maybe it will help.

I was surfing around and was at http://www.suzzoos.com/
Read the link on the left about caring for zoanthids. They offer some info about the "fungus."

Will this fungus spread to other corals than zoas?

There's another thread going on here somewhere - check out the zoaid.com site for something called "zoo pox" there's some good info on there and i think some success in a furan 2 dip if i recall correctly but it isnt fresh in my mind atm

I havent made a post about this but I recently had an explosion of this fungus....... I lost about 5 colonies and dipped in absolutly everything known to man.

So far my best treatment was with myacin one in a 5 gallon bucket. I used about 1 gallon of water per myacin tablet.

So far it has eradicated the fungus completly

Perhaps it looks like a fungus but is a bacteria that mayacin could kill?


I read in another thread when I searched earlier that theres a certain time o fyear when this stuff happens from like nov-feb or so .. in the past years people report having this problem around then.

pretty strange

"White fungus" normally happens due to a lack of water motion or an injured polyp/colony.

Some times dead organisms around the polyps could develop that too!! When sponges grow around the bases of the polyps they need to be abele to survive. Dead sponges could lead to fungus' growth and therefore spread to the polyps. Sponges normally die because of lack of food and elements (filter feeders) and/or water flow. They die during shipping too, so it's a good idea to check for them when the new frag or colony arrives, prior to introduce into the system.
I found the regular use of iodide, amino acids, vitamins and trace elements (water changes are normally enough!!!) could help some of the species of sponges in closed systems. There is so much more to sponge keeping and I really can't go deep into it because I'm not an expert. I'm not an expert in zoas either!!! It would be good to search, if you're interested! Other very wise option would be to prevent the growth of any sponges in the system, if you're really concern about them dying among the polyps.

Other times, after years free of "fungus disease", the tank could manifest it after an accidental injury to one or more of the polyps.

I've had that "fungus disease" when the system got to a type of stress too, like changes in salinity or alkalinity, with a high organic content. The areas with slow water motion will develop the disease faster!!!

Some of the dipping treatments I've heard that could work against it are with: Lugol's solution, strong iodine tincture, hydrogen peroxide, Maracyn 1 and Furan 2. But you can do only with the frags. Please don't use any of these in the tank. It needs to be in a dipping fashion. Make sure you're dipping properly. Search for dipping practices for zoas.

I normally use Lugol's solution: 8 - 10 oz of tank water (or fresh water) for 3 - 5 drops of Lugol's solution for 3min. Iodine tincture could be used also in the same rate.

Yes, temperature could help to prevent/slow down the disease. In systems with temp. between 75F - 79F should be less prompt to develop the disease.

Normally the polyps begin to develop the "fungus" from their bases and some of the times they detach from the rock ending up all around the system. Some other times they just waste away turning dark gray or black, shrinking/melting. I believe the tow forms to be different pathogens. I also believe there is more than 1 type of "white fungus disease", showing different speed rates and different types of structure. Some are more white than others too.

We don't really know if the "white fungus disease" is really fungus. It could be a bacterial infection, but it's called "fungus" because of it's appearance. I don't know of any scientific proof that would say it's really fungus after a microscopic examination, to this date.

Best way to avoid that is to prevent introduction of the pathogen in the system, dipping every new colony in Lugol's solution. Some say Coral RX is a great preventive dipping solution also. Please keep in mind that even another type of organism, live rock or even plain natural sea water would be enough to introduce any microscopic pathogen to the system.
A good water flow will be one of the best things you can offer your zoas!!! To dip and quarantine the new zoas is the best way to deal with the problem, eliminating great chances of having it!!

The type of fungus found in zoanthids are probably basically the same that live rocks will have when there are dead organisms in it, like for example sponges or some type of algae. The smell is terribly rotten.

I just wanted to participate in this thread...
Stay safe and keep zoaing!!

Man, you are right about that. I had fungus on a frag. I washed the fungus off but the infected fungus smelled horrible. I'm keeping it in quarantine and treating it with furcan. glad someone else noticed the horrible smell.
