How long can Zoanthids stay closed?
As long as the retracted polyps remain robust with no signs of bleaching or degredation, you are fine. Just keep everything constant and maybe prepare a well aerated water change and a day or 2 of complete darkness.
Why are my ZOA corals not opening?
Nitrates and phosphates, Alk and lights all must be in balance or corals are not happy. Low nitrates you want to have low alk and back your lights off. There’s nothing for the coral to eat so blasting it with light will just burn them up. High Alk with low nitrates can chemically burn them also.
How long does it take for zoas to open after Fraging?
4. Within a few days the zoas will settle down and polyps will open, the coenenchyme will begin to form itself to the plug/rock, and within a few more days the new colony will be attached and beginning to send out new stolons. After a few weeks your new frag is ready for swapping or addition to your display aquarium.
