Hi All
I got this frag from a store. the salesman told me that it is sun coral. However, I tried to feed them for many days but didn't see it come out even once.
Is it really sun coral? I googled but didn't see any similar.
Thanks,
Tyler

It is NOT dead. It is a black Tubastrea. Black sun coral. Sun coral can be harder for many reefers to keep as it is non photosynthetic and requires feeding to each polyp.

They are often found upside down growing under an overhang or cave entrance. So get it out of the light and into a shaded, moderate flow area.....sometimes they are hard to get to open.

Your best bet is to try feeding it at the same time everyday. Try and coax the feeders out at the same time and you can train it so to speak, but the initial opening of the polyp is the hardest to achieve. if you can get that, you may have a good chance of longevity with them;
 
Thanks! It's now under the shade..I'll try what you suggested.
One more question: brine shrimp or "regular" shrimp at Giant Eagle? I crushed the shrimp (that we eat!) to make the water cloudy and feed the corals these cloudy water containing tiny pieces of shrimp
Thanks.
 
there are much better options than the shrimp you would get at the seafood counter for your fish and corals. typically those kinds of seafood are reserved for starting cycles, larger predatory fish like lions or triggers, or in the case of clams picky eaters or specialists.

adult brine shrimp, even gut loaded ones, aren't the best source of nutrition. they're fairly devoid of most important nutrients. freshly hatched (live) brine nauplii can be a very good supplemental food source since they still contain their yolk sac that has a lot of good protein in it.

i feed my fish a combination of foods.

New Life Spectrum pellets.
PE Myses Shrimp.
Nutramar Ova.
Live brine shrimp nauplii.
Nori for my tang and blenny.
Frozen Cyclop-Eeze.

i usually feed some pellets and nutramar daily. after soaking the nutramar in some Sera vitamins. then a few mL's of brine shrimp nauplii in to my feeder for my mandy (and whoever else steals some). then once every week or two i spot feed my corals with PE Myses. once every couple weeks i will treat with some of the frozen Cyclop-eeze for everyone. i feed less of the cyclop-eeze because the frozen stuff only comes in huge whole sale sized bricks, or in split portion packs with PE Myses, and it goes much faster than the myses does.

the only reason i am on such a lax schedule with my coral feeding is that all of mine are photosynthetic, and i only supplement my LPS with feedings. your requirements for a non photosynthetic coral, as mentioned by others, will be considerably different.

they will also probably be best off if you use a dropper or syringe to target feed them directly as opposed to just broadcast feeding the entire tank.

what part of shadyside are you in? i work right near Melwood ave.
 
Thanks for sharing your experience. Yes I use plastic transfer pipette to feed the sun corals only. I am near Walnut st.
Hope my sun corals open up some time soon...!
 
Thanks! my sun corals are dead i think. the black stuffs inside came off... :(
I am gonna get some more and hope they will do well next time..
 
If it were me I might consider waiting on getting more sun corals. They're notoriously tricky and might be better left until you're more familiar with your tank and routines.

If you want I have some Xenia and Kenya tree frags I could give you. They're both damn near bullet proof, so good to start with, and have nice movement.
