Mushroom or Kenya Tree killing my Zoanthids?

[NanoLover]

Those zoanthids and mushroom have been there for a couple of months. The kenya tree has been there a while, but has recently gotten taller. Is one of those causing the zoas to look eaten/burned or could it possibly be something else? Nothing else in the tank seems affected, including other zoas. If I move them, should I discard the messed up ones?

I think those are actually a variety of Paly ,IMO but I could be wrong. In any case I believe that it is your shroom that is irritating the polyps.
Have had some of mine get scarred like that. I would let them be , even if they do not look perfect. They will still help build and multiply your colony.
Is the mushroom attached to the same rock as the paly/zoanthids? If they are and you want both corals it would probably be easier to move the mushroom.

They look irritated but the kenya could be shading them too much. I can't really tell but I would start by moving a few things around if you can.

I agree that those are palys not zoas. The long, thin tentacles are a giveaway. In my experience, palys kill mushrooms every time. I had a rock full of mushies similar to those that was a little too close to some green palys and the whole rockful melted away in a few days.

I don't think the Kenya tree should bother palys or zoas, either. I have KT all over my tank and, in fact, I'm looking at a stalk right now thats lightly brushing up against a colony of delicate zoas without bothering them.

The point is, palys are really toxic and usually win most matchups against other soft coral intruders. After looking at your pic again, I really don't think those are necessarily burned. I have a huge colony of some just like that and they have always kind of been folded and fringed a little on the borders rather than perfectly round. I've always liked that about them and the way they line up to form a big colony.

But by the looks of it, that mushroom is going to lose that battle.

Thank you all for your answers. I will move the mushroom. I have quite a few of them, but only one little spot of those palys. I called them zoas because that is what my LFS labeled them as. Anyway, I hope the palys make it because they used to be really beautiful. They were an odd shade of green with a cobalt blue skirt.

I have a very similar paly. I like them they are a lot different then the more common brown button polyps. They can be very invasive so be careful where they are placed . To create "frags" simply lean a clean plug or piece of LR against the colony. They spread very quickly on to the new territory.

They are pretty cool paly's. Had a couple on a big zooanthid rock. For some reason the zoo's eventually melted away over a couple of years then these just started multiplying like crazy. now I got hundreds.
