Are these Favias goners?

[LeafsReefer]

These Favias had been doing well until they started getting cyano on their edges. I blew it off a few times, but now they are looking like this. Is there any chance of saving them?

Hard to tell due to blueness but I’ve had coral in worse shape come back. Pics in whiter light or with a orange filter would be helpful

I still see flesh and color. They have a chance.

need better pics in white light, but I still see flesh, so still possible to recover. Would need all the details about your tank to offer more suggestion; how old is the tank, what are the water parameters, what type of lighting and flow, any other corals in the tank and how are they doing?

I have a 5" diameter favia that was healthy and growing and then for some reason went down hill until all but 2 polyps were gone ( white skeleton). I left it alone and then after a month or so I noticed there were 2-3 new polyps over the existing white skeleton. After a few months the favia re-populated the entire original skeleton and is now spreading.
Don't give up.

Do these pics help? There's 1 torch, 4 zoas, 3 polys, 4 Florida ricordia 1 blasto and an aycan. All are good except for the hammer, but I think that was a placement and seems to be doing better since I moved it. The favias were good until the cyano got on it.

Always can thrive again if stress is removed.
