Need help with runaway zoas

[doliver]

I have a few zoa colonies that are growing faster than I can count them -- the problem is that they're up in my rock structure and I'm afraid that a few months from now, they'll have overrun everything.

They're already on rocks that can't be removed without breaking up a couple of other corals. Is there any effective way to control or stop the spread of them without taking the rocks out of the tank? And if I try to do some cutting/scraping/scrubbing with the rocks in place, do I need to worry about palytoxin getting into the water?

You can opt for natural zoa predators , but thats the extreme. I think scraping is the only option. If you have a lot of zoos to scape just wear mask, eye protection and shoulder length gloves. Don't know the extent of palytoxin, but from experience, its not fun and can last for weeks. just remove the rock as much as it sounds like a pain, it gives you the chance to correctly remove them plus you can aquascape to a better look?

If you end up with some zoas that you don't want, I would be interested, if they're colorful. LMK if you end up with any.
Thanks

Honestly, and not harping on you, ALL corals will "overrun" others etc etc, it's just a matter of how fast it will happen. If you're really that worried, break the other corals to get them out, you can reglue them and they'll continue to grow fine.

sell your rocks and buy new rocks

I had those and it worked for me untill I pickup some wrasse and they ate all the predators. But the predators only work if you have lots of zoa otherwise they will wipe out what you have.
