Feedin my corals

[soulsigma]

I feed my corals at night with only the moon lighting on and I noticed that with the exception of my chillie coral all the polps on the remaining corals are closed. My question is aren't the polyps used for feeding ? and how are my corals eating if their polyps are closed untill the lights come back on?

most coral eat during the day, Nephthyigorgia (Chili Coral) is a night time coral, polyps are usually only out at night, really, you dont need to feed any Photosynthetic corals, it just leads to phosphates in the long run.

I'm not sure of which corals LegendLand is talking about, but as far as I've ever understood it, most corals that open up at all (sun corals, favites, platygyra, and many other "LPS") open up at night unless trained otherwise. Things from the euphillia family will be open during the day, but don't close up much at night either, so they'll generally take food 24 hours a day.

Soulsigma, which corals are you looking to feed at night that aren't open? Were they from the wild or tank raised? if tank raised, they may be used to eating during the day.

but few are night feeders, yes favia is one photosynthetic coral that feeds at night, sun corals are non-photosynthetic

I have a Sun coral and he open at day and night so he eats everytime he have the oportunity. (I feed him almost every day...) But i have a candy cane and i have to wait an eternity for him to open at nights to feed him...=[

yup. my candys open up at night also, but everything else closes (zoos, palys, frogspawn, hammer, torch etc.) heck too bad for the canes though because i dont feed at night lol.
