How to kill zoanthids

[ReefGeezer]

Help. Zoanthids are taking over my mixed reef. The tank is too crowded with breakable corals to use bone cutters. Is there a way to slowly kill them off? Maybe Aiptasia X?

How large of an area?
Are there palys within the group?

you trade the rock to your lfs, facebook group, local reefing club and start a new rock.

The main formula I use is this:

*Really try* to grow them in a tank with lots of other successful corals. They'll die almost in a heartbeat.

BUT...

Do NOT give up on them while they're dying or they'll make a huge comeback.



Zoa's have more personality than any other coral IMO. (That's not a great thing. LOL)

You could always add sundial snails... they eat zoas. They are considered a pest though.

Maybe some zoa eating nudis as well.

I just inject them and cover them with kalk paste. Do only small batches at a time so if they let off toxins it in controlled amounts.

I have a ton of SPS and ZOAs. I keep the zoas on the rocks on the bottom so as not too have issues. However, some times one grows faster than another and over takes it, or thhey just grow too much and reach rocks I don't want. Those get nuked and I've never had an issue.

Also, you can get a hose and stick a rigid piece of PVC pipe cut into a sharp end. Siphon as you scrape them off the rocks, then nuke whats left. Lastly, I've had them die back on their own from being overshaded by some stags of other sps.

They do need light, so I would guess you could just cover them, up with something in some areas.

This is probably the responsible way to do it :)
