Mark can you give me any tips on how to get sun corals to open up and feed. I have tried the soda bottle trick. Feeding in the morning before I leave for work with the lights off.
never any luck. Right now I have a black sun coral and having the hardest time with it.
Hi, I am sorry that you are having trouble with your sun coral. Most of the time it just takes time and patience to get them to open and feed, but sometimes, especially when coral is on the bring of starvation, it might not have any more energy to extend their tentacles and feed. I hope with yours it is not too late. When I get new sun corals , they usually don't open right away, most of them were not feed for some time, so it is very important to get them to feed as soon as possible. What I do is feed them in small container out of main tank. You take water from your DT and put your sun coral in a container with it and flood it with food, I mean a lot of different, frozen food. I use combination of mysis, brine, cyclops, etc., make sure food particles land on coral itself, even if tentacles are not out yet. Leave it in it for some time, I usually check in about 20 min. , stir the water with food a little to get movement and leave it again. I do this for 1 hour, after that I put coral back in DT. If you can, do this twice a day, it might take few days but soon it should be opening and feed. Once it opens on regular basics you can try to feed it in main tank. Make sure to feed every day for some time to get your sun coral back to health, after few weeks feedings every other day with meaty food should be fine. I feed mine every day, weekends twice a day. They grow new heads really quick this way. I hope this will help you get your sun coral back to health quickly.
Here few pictures of how it is done
Got this starved sun, did not look too bad but did not want to open in DT, so in a container it goes.
