Fungis?

[Jarred1]

A few days ago I started to notice that one of my zoas had a brown film on it so I cut the infected polyp off and a day later a few more polyps had this film on it so I just threw the colony away. Today I found that another frag of zoas has what appears to be the same fungis so I cut the infected polyp off and threw it away but before that I took a pic of it. I would like to know what it is and what causes it? I found something similar to what it was but that thread doesn't have pics:

Fungus?

Fungus?

It is called RTN = Rapid Tissue Necrosis for lack of any known fungus. I had a gonapori that died the same way. I don' know if their is a cure except for what you did. Dips in some Coral RX may help after you cut away more than just the affected area. It has been known to wpie out whole colonies . I would start doing the largest water change that you can do immediatly to save your other corals. and look in the stickies for RTN. Good Luck and keep us posted..:wildone:

I thought RTN was only for SPS...

I'd dip it in some iodine/furan 2 and get some flow on it asap, the only way to get rid of that stuff is dips and flow, and it spreads fast!

 

[Jarred1]

what is that stuff?

furan 2 is an antibacterial/fungal treatment for freshwater fish, but has been used to treat zoas for diseases and fungus.

Iodine, I don't have too much experience with, but I'm guessing its Lugol's iodine. There was a recent post about dipping zoas that may help

Edit:

Here's the link

Instructions for using furan 2 can be found on coralpedia.com

Good luck!

I'm sorry, I know what furan II does and the same for Iodine. I want to know what is wrong with the zoas.

It almost looks like cyano to me (not saying it is cyano) but I have seen it on my zoos before. Dips, and a light scrubbing with a tooth brush seemed to help. As organism said I found that zoas in low flow areas were much more susceptible to that then zoas in high flow areas.
