Favia coral with problem?

[Gibsh]

Hi there, recently purchased a fragged price of a bright green favia coral and a corner of it has a white what looks like mouldy area. My question is first what is this and secondly should I try and remove the piece that is 'infected'?

Conditions are all good and parameters are within good levels, other corals (acan, gsp and Duncan all recently introduced are doing fine.

Many thanks and feel free to move this to the relevant forum if there's a specific one for this but as I'm new to the hobby I thought it would be best here.

I couldn't ID the infected tissue you are referring to. Lower right perhaps? The majority of polyps look fine to me.

If some tissue is peeling off, I would brush it off. Make sure you have good flow across the coral but not too strong. Vigorous but wide flow is best IME. I've also put a drop of hydrogen peroxide on the cleaned skeleton, let it sit for a minute or two, rinse and then back in the tank. Some administer a drop of iodine. Some just cut off the decaying part if things look to be expanding. I would keep an eye on it and take action if it seems to be spreading.

The LPS forum on RC is a good place for threads like this. Check out a thread called "Coral Rescue". Many examples of horribly messed up corals being brought back to health. Also look into "Brown Jelly" disease so that's not what you have.

I had a very similar issue with a Goniastrea. Take it out and put in a Tupperware container with tank water. Swish it around real good or use a turkey baster to remove the jelly like necrotic tissue. It will stop the recession. You can also do the iodine dip mentioned above.

I wouldn't do hydrogen peroxide unless it's a last resort and you may lose the whole piece regardless. It could stress it to the point of death.

You could also frag it off if you have a Dremel or band saw.
