The tubastreas are such an addiction for me. I have beautiful photos of of them thriving and growing from such tiny things! I’ve had the pleasure of nursing a few sick sun corals back to health. There is one food in particular that seems to do really well for them. San Francisco Bay Reef Plankton Mini Cubes is a food that mine have all taken very well to. The variety of foods in the mix as well as the fat content seems to be something they appreciate a great deal. It is a tank polluter though, so a very good cleanup crew is absolutely necessary.

@Daniel – Mine are all trained to come out during the daylight hours. Sometimes they will not open up for weeks once newly introduced, but with some patience and the right food for them to detect during feeding times, their own biological clocks will sync and they will open early to prepare for your daily feedings if you are feeding at the same time every day consistently. Hope that helps.

Is there any way that I can get it to open up during the daylight hours? Or do I have to wait for them to open up by themselves to feed? What would you reccomend feeding it? I currently feed my tank with frozen brine / mysis shrimp, marine snow, and phytoplankton. I also made a home made marine mix using scallops, shrimp, haddock and a rew other fresh seafood items that were soaked in selcon, and frozen.

It wasn’t my sun coral – it was a blogger on YouTube.

Unfortunately, I believe the sun coral died. If you follow the YouTube video above back to YouTube then click on the poster’s name you’ll find another video where he says it sadly died.

I hope the tips above might help? Sun corals are a difficult species to keep alive due to the need for a lot of spot feeding, and also the consequent water quality issues.

Good luck!
