[muggle0981]

Was trading some corals with a good man-and he threw in a single head black sun coral

Any special care-how hearty are they? Crappy pic but was suprised tentacles out

They are hearty lps. I had a large 15 head branch that took over a year to die because I didn't know what to do at the time. The key is to feed alot but keep nutrients in check, it doesn't use light. High in, high out

Yes seems like feed it and maybe will live

Without fouling your water quality...

Easy care - Very low light in moderate to subtle water flow and feed mnysis shrimp

Non photosynthetic. Light not primary source of nutrition.

I Feed every other day directly, when polyps out after dark.

Likes flow.

You can train it to be open during the day.. to get it to open, "tease" the water with some food or garlic, give it a few minutes to start opening. Repeat until it opens up, then target feed. Do this every day at the same time, shifting earlier and earlier. Sooner or later it will stay open most the day. Dendro is another exquisite orange specimen that is very hard to kill, with sane requirements..

Fun fact: There are actually two species of black sun corals: Tubastraea diaphana and T. micranthus. T. micranthus grows large arborescent branches and is usually found on reefs, while T. diaphana (from what I can tell) grows in areas with more sediment and under overhangs.
What we can gather from this is that T. micranthus likes higher flow and lower nutrients, while T. diaphana probably likes lower flow and a little more nutrients.

Which one has the green tentacles?

T. micranthus, I think. T. micranthus also has a dark green coloration to its coenosarc
