When do new zoanthids typically open up?

Been a week now, still waiting on some of them to open up. Got a few Radioactive Dragon Eye and Red People Eaters that are partially opened, but the rest are still closed tight.

Just got my first order from Aquarium Depot (akareef2go) - a bunch of new goodies. It's been about 24 hours now, and I'm seeing just a few polyps popping out here and there. All the new additions are placed low in the tank. Had some mixed results with the inverts - 2 Tonga snails made it just fine, but sadly, 1 scarlet didn't survive the shipping. Also got two blue claws that were supposed to be XL, but let's just say I'm glad I didn't get the regular size...

My first coral order online was Reefs2go, over 2 years ago. Now I get all my coral from local places, Kush Corals/Chicagoland Aquariums - they're just 10 minutes away. I got one of those Reefs2go easy coral packs back then. It had dragon eyes, palys, peach apples zoos, a mushroom or two, and some GSP. The dragon eyes took a while to open, but the peach apples opened fast, almost as fast as the GSP. The palys didn't do well, but they replaced them and the second batch did fine. The shrooms multiplied like crazy under my AI prime. Good luck.

I've generally had a good number of zoas open within the first 48 hours, but I'm with you on the salinity thing. High specific gravity levels can definitely cause them to stay closed. Hopefully, your adjustment will help them all come around.

Flow's key, more flow's better. You'll be surprised how much they really need it. They should open up within a day or two, just give 'em time.
