[Porkchop95]

So I’ve had this section in my tank for prolly going on 3weeks they where doing great but I don’t know what happened but they closed up a couple of days ago and now they won’t open up anybody have thoughts why or am I worried for no reason

What are your tank parameters? Specifically, alk, calc, mag, nitrate, phosphate, salinity, temp, ph? Do you keep a log of your water parameters and have any of them changed dramatically? Have you changed/added anything to your tank such as equipment or livestock? Did you dip or inspect for pests such as nudibranchs and spiders? What kind of PAR are you giving them and flow? How old is your system? How are other corals that aren't in this one section doing?

There are many reasons why they could close up. Details and pictures help a lot.

Sometimes zoas will close up when they are adjusting to new tank parameters. Did you inspect for any pests that might be irritating them? Pictures can sometimes help id the problem.
