Is this zoa done for?

[najer]

I've heard of zoa eating nudis but never snails. Someone enlighten me, please. I need to know more about this.

Search sundial snails.
I've had them, you defo don't want them.

I had sundial snails destroy a beautiful zoa colony. I crushed the snails with forceps. Once I got rid of them it took 8 months but the colony started bouncing back. Never give up on a zoa!

I had to qt all my zoas for about a 6 month period a few years ago, lost about 80%.

I've been reading more and more about these dang predators. It's like treating human head lice, you can't give up!

I would also take them out and dip them and get an artists brush and give them a gentle but thorough clean. Use a turkey baster or large pipette to blow dip water into all the crevices in the rock.
What is your flow like, cyano also likes lower flow?

I use a child's super soft toothbrush. I've also got a 14 inch long glass pipette to blast critters from under the polyp.
