Love mine did not really know much about it when I bought it but it was pretty and yellow and looked so good sittin in that store I thought Gotta have that . Izzy helped me get it start feeding and hey its one of my fav corals in tank now. Try that black sun bet it looks pretty cool , never seen one though.
"Earth, our Water Planet, is the only planet in our solar system to be endowed with appreciable quantities of liquid water. Life, born in the water, must be at least as rare as water in the Universe, and as such must be revered, under any of it's forms, as a Miracle."
Dont know if anyone can learn from me or not Izzy but I know they can from you. Sun coral is open and fat and babies and storks and all that good stuff now . Thanks again.
Welcome to the world of non-photosynthetic animals, Lucky!
You'll love it once you figure it out. All of the ones I've had wouldn't open either when I first got them. In order to persuade them to open, I removed them from the system in a half-gallon glad ware container, and crushed up flake food, placing a small sample of the flake dust into the container. In a few moments, they'll begin opening, if you're LUCKY! HAHA! Pun absolutely intended!
Now is the fun part, pick up some mysis, and soak it in selcon for twenty minutes while it's thawing in a cup (don't add tank water to the food, until the selcon has been there for twenty minutes.) Mix up the food with a little tank water, and use some tweezers to gently place one or two pieces of shrimp in the tentacle of each polyp. Be gentle, because at first they will be very shy, and close up as soon as you touch them with anything other than food (i.e. the tips of the tweezers.)
If you hit them about three times a week in this manner, you'll eventually have them opening at the same time every day. Another mistake commonly made with Sun Coral is placing them under a cave, out of the light, and out of the flow. They are quite tolerable of all lighting schemes, including halides, and all flow regiments, including the most rigorous. Placing them out in the open flow and light will allow them to eat phyto and zoa that naturally grow in the tank.
If youd rather not remove them from the tank, turn off all the current, and spray some of the water used to thaw your shrimp over the sun coral. In a few moments, they polyps will open. Using a turkey baster, you can gently blast the polyps with some shrimp and watch them take it in! Its rather interesting to watch.
You may have to fight off the fish from stealing it. Ive cut 2 liter bottles in half, and placed them over the coral to protect its food source from predatory fish. If you remove the lid, its easy to stick the baster into the bottle and spray each coral you are targeting.
Don't think this belongs in sps forum but , Izzy I can't get my sun coral to open at any time . I know it is a night time coral and I have it out of bright light but it has not opened . I bought it a few days ago , so help me out before I have a sun skeleton.
