Sun coral
Hey everyone,
I got a sun coral recently, and I know they are non photosynthetic so I put the colony back in the shade. The only issue is that there's not a whole lot of flow, and it's not very accessible. This makes feeding difficult. How much light can they handle? Will it hurt the colony if I put it (still in the sandbed) in a higher light area? I just want to make sure that the colony doesn't starve.

They are nocturnal and usually deploy for feeding at night in the wild. They will have to be fed individually from now on to prosper. They are beautiful, but a pain to keep fed IMO. I would keep them out of direct light if possible.

Darkness and decent flow. Each polyp needs fed as Greg said. A total pain...the issues in my tank started when I tried to keep a small one. Opps...

I have three colonies. One is shaded. One is midway in the tank. The third is in the top third. I feed a couple times a week after I add coral frenzy (about an hour after the lights go off. I find that the fish are less apt to steal food from them.

I just hate that filter feeder food. It's liquid phosphate in a bottle. That's my main reason for not keeping azooxanthellate type creatures.
I suggest being very specific towards feeding just the polyps that need it. As too much of that stuff will tax your filtration.

I have one on my sand bed in full lighting. In my limited experience it prefers flow over shade. When it first arrived I would pull it out daily(try around the same time) and put it in a container with a lot of food. Took a while so you have to be persistent (over a month but I missed some days because that's just a lot of time, may go faster if you are more consistent). Now it opens most days around the same time and I have a cut water bottle I place over it after target feeding the polyps so the fish don't steal the food before it eats. This is another reason it's out front because I need room to fit the bottle over it. I really basically feed my NPSs now and the fish get the leftovers. And it can eat pretty large pieces, you would be surprised.

That's sounds like a very good approach to me.

melosu58 has had a sun coral colony for a long time and has never fed it directly. I prefer to make sure all polyps get meaty foods, so if i keep them, I keep them in reach.

Are they just grabbing fish food in his system? They had to have something to eat.

I don't know...i don't think he broadcasts much their way.....but you know corals do absorb nutrients through their flesh, right? this could possibly be what's happening here.
