Sun Polyp not opening

[Krabby]

Hi,
I just added a Sun polyp 2 days ago.
It still hasn't opened. Does it take awhile before they extend?
It there a way to tell if it is dead?

got a pic? you might try enticing it with some food, spray it towards its mouth the powerheads off.

They only open when feeding, and you need to feed it...

i saw another reefer spot feed one before. he cut out the top of a water bottle, placed it over the suncoral, then turkey basted some phytoplankton into it. that was the first time i ever saw a suncoral fully open. these guys need spot feeding. i would keep it out of direct sunlight as well. mine only opens up at night when the moonlights turn on.

Yeah I finally saw it open last night for the first time.
I had it in direct light. I didn't realize it needed shade.
Anyway I moved my LR around in order to provide a little cave area for it.
It should be a lot happier now. Of course I can barely see it in there amongst the rocks. I also spot fed it with a spare turkey baster last night.
I'll keep that up and see how it does.
Thanks for all the help guys.:top:

I have a 40 polyp sun that is bigger than a softball. I have found that the light is not the issue, the current is key. I moved mine from a cave to a plastic hanger I made. It is 6 inches under the surface and in the light. I hold a bit of frozen plankton in the current for a minute, and in 10 minutes it is wide open. Also, phytoplankton???? Mine consumes frozen BRINE and MYSID. About half a cube per feeding. To avoid fowling the tank, I feed the sun and the fish get the leftovers.

Hmm, I may need to move him again then. So I can at least see him.
Yeah the LFS told me to feed it Phytoplankton. But I also have the frozen cubes. So maybe I'll try that. Thanks for the info.

 

[RIPreef]

No problem. Love mine! Truly a beautiful addition and worth the extra care. Oh, and I entice it with zoo/cyclops/rotifers... not phyto!
Good luck.

I'll move him out a bit 2nite and try the cubes

In the wild sun coral grow on the roof and walls of caves in high flow areas. The do not mind light but can easily get over grown with algae in well lit areas. You can train them to open during the day by feeding at the same time each day. but just a little food in the water until they open up then feed them once fully open.
