Zoanthids won’t open

[SaucyJuicySteak]

Had them for a couple months now, and they never really opened up, I also noticed cyano on the frag that seems to be annoying the zoas, any ideas.

I'd dip em in some coral revive with an air stone. Also, do you notice any fish pestering them?

I dipped em a few days ago, didn’t see anything come of of them, I haven’t see any fish pestering them but I do have a melanerus wrasse

When I had zoas that wouldn't open up I'd do a quick 2 min freshwater bath then a 10 min iodine bath and presto they would be open the next day

Sometimes tank placement can be an issue as well. If they are light stressed they will stay closed up. Maybe try moving them to a lower dimmer part of the tank

I bought 30 colonies this month 20 were dipped and they open half the time I freshwater dipped other 10 after dip and they open up a lot better and faster freshwater dip all my colonies from now on after dip
