Black Sun Coral

Tubastrea micrantha dying slowly!

Tubastrea micrantha dying slowly!

Ok, I'm a new member and I have been reading everything online that I can find about my Tubastrea micrantha and nagging everyone at my LFS about it. I've had it for about three months and it is slowly dying. I did the Tupperware method for a while and when that baby finally started putting out its polyps it was a joyous sight! But my LFS guy was horrified that I was doing this and told me to stop. He sod me one of those long tube things and told me to feed each head daily using it. He also told me about cutting the bottom off a coke bottle and putting it over it when I fed it and to put it underneath other coral to give it shade. So ... I can't feed every polyp with it under an overhanging rock, nor can I put a coke bottle over it in this position! Now I'm reading to put it on the substrate but to give it good water flow. How do you give it good flow on the bottom? My fan, protein skimmer and bio wheels are at the top of the tank. And I decided that feeding each polyp each day was WAY too high-maintenance for me. So, now, it's starting to turn white and I can't make the polyps extend at all. One day, in frustration, I took frozen mysis shrimp and smeared the ends of the tubes with it trying o force feed it! LFS guy said not to do that again. I went back to Tupperware feeding it but no results this time. Paid $69 for it and hate to lose the money and hate watching it die. Main fish guy wasn't there when we bought it so we weren't warned about any of this. Any suggestions? Everyone else in my tank is very happy, I've gotten rid of all the cyano algae and all the hair algae and just have a lot of the good purple algae.
So here are the questions I have:
1. On the ground with low water flow or higher with more flow?
2. Under an overhang or out in the open?
3. When people say shrimp do they mean live shrimp or frozen cubes?
4. Tupperware feed or don't even touch it?
5. If yes to Tupperware, how long do I leave it in?
6. Someone said they let it float in a bowl in the tank. What do you mean?
7. I'm not going to feed it at night. It's going to hae to eat during the day or die. Schedule is too irregular to train it with a regular feeding time. Suggestions?
8. What do I do about all the food in the Tupperware bowl? Fish loved having it dumped back in, but my purple algae did too d became a nuisance. Yes, I have an adequately sized protein skimmer.
In other words, I don't want it o ie but have very limited time to devote to it. Never would have bought it if I'd known how much work it would be.
Help?? Thanks!
 
All I can share is my experience...mine are on the bottom with high flow. They get fed every other day, alternating pellets, mysids, cyclops... They have gone from 3 polyps to over 2 dozen

What are you using that gets high water flow at the bottom of the tank? My fan is at the top, left-hand corner against the back wall. Should I move it?

What kind of pellets do you mean? Are the mysis and cyclops frozen cubes?

How do you feed yours? And do you turn off your fan when you feed them?

Thanks!
 
limontee, go back to the container method. Put it in there (with SW of corse), put some food over it, leave it for 30-45 minutes at minimum. ( I leave mine for 1-2 hours for it be able to eat) Come back and if it hasn't opened, put it back in the tank and try again the next day. If it has opened, leave it a little bit longer so it can eat.

It might not open in your tank. Mine still doesnt open (I've had it for 2 months) unless I put it in the container.

Yes, mysis is frozen. If you get PE Mysis, cut the larger ones in half.

You can just use a powerhead to get flow wherever you want, but be careful not to disrupt the sand bed.
 
I was given a black sun froma nice LFS owner who new I'd had success with the orange suns in bringing it back to life. It's got probably ten polyps on it and they were hollow and jagged when I got it. two days and five feedings later its beginning to fill out though still no polyp extension.

Those of you with black sun corals, how much extra care do they need compared to orange suns? I picked the black sun coral up at the same time as a very much worse off orange sun but after five feedings its looking happier then the black sun coral and extending.
I have a large sun coral colony with 40-50 polyps, which is fed everyday I'm assuming the black sun coral would ahve similiar requirements? mounted in the shade or in a cave, fed every day with a range of meaty foods?

Oh and are they able to be trained to extend during the daytime? or are they more light sensitive then the orange suns?

There doesn't seem to be much info on the net about them, apart from their harder to care for then orange sun corals and have a lower survival rate.


I have about fifteen colonies of black sun coral now and I have not noticed any greater difficulty in caring for them than the oranges in fact I have had faster shock recovery from the black ones than the orange ones I have noticed though if they are underfed they will lose tissue usually on the shared skeleton but the individual polyps will still thrive and even bud. I have not yet had a colony regain its "shared" skeleton tissues but the colonies that are fed well don't experience this loss. ime the black colonies also have been easier to get adjusted to feeding than the orange ones. I do buy the sand grain idea for individual polyp loss that seems to be very true. also ime the colonies on an individual branch with short polyp skeletons do better than the clustered branches (like a bush) but on a side note I am very guilty of overfeeding my tanks to ensure they all get access to food so maybe I am just seeing coincidences. I do not take the time to target or hand feed my sun corals the way I do my dendros the dendros I cut silversides up into bite size pieces for and hand feed each head every three days I have not needed to do anything like this for my sun corals.


and no I have never gotten (as hard as I try) to get them to daytime feed or even open but give me a few more months :lol:
