cup coral not extending

meisel1 · 04/26/2006, 07:18 PM

Yesterday I purchased a cup coral apperoximately 3" in diameter and carefully acclimated it to my tank{1/2 cup water in 1/2 cup water out over one hour}. The problem is the polyps are not extending fully. The coral is in moderate light with moderate flow. lighting is 260 watts pc light and it is about 8" from the surface and I'm wondering if thats the right place for it. I don't want to lose this piece so any help would be appreaciated. My water params are ammonia 0 nitrite 0 nitrate 5 ph 8.2 dkh 7 kh 3.5meq/l temp 79.5F calcium 420ppm....cheers

dont know much about cup corals... but here is a free bump for you maybe someone else knows...

Can you post a picture of the coral? Or post a link to a picture of the coral you have? I've heard too many different animals called a "cup coral". I'm not sure what you have.

The problem with bumping a thread is that the bump takes it off the unanswered list.

Are you taking about a Pagoda? From previous experience they need some flow.is the coral getting some flow at all?

meisel1 · 04/27/2006, 04:17 AM

the coral is also known as the pagoda coral and yes it is getting moderate flow.

give it a day or two to get adjusted to the new tank.

Okay, I agree that the coral might take some time to get acclimated. Turbinaria peltata is the scientific name, I think.

Correct bertoni it is called turbinaria.I have been looking for info on this coral but cant seem to find much. I need to know what this speices needs to thrive, like lighting, feeding and placement.

My pagoda cup took a good three weeks to show any polyps and then another week or so to fully open. Be patient. If you think the flow and lighting are good leave it be. Mine is one of my favorites probably because I had to wait so long.

I'm quoting from:

[ericsbook]

because I haven't kept Turbinaria.

First of all, you might not have T peltata, but hopefully that won't matter.

So your coral might prefer reduced light levels. You'll want to flush detritus out of the cup to prevent diseases. The further the polyps extend, the better the water quality. Nothing special beyond that, although it'd do better with some feeding, like most corals.
