July Coral of the Month - Sun Coral! Type: LPS Origin: West Indies, Bahamas, Africa, and mostly imported from Indo-Pacific. Aquarium Needs Lighting: Of no consequence. These corals are not photosynthetic and lack zooxanthellae. Water Quality: Good to high. They can be sensitive to nitrates. Current: Moderate to strong. Feeding: Require regular feedings 2-3x a week. Will accept frozen foods such as mysis shrimp and brine shrimp, or reef snow. Will also filter the water for phytoplankton. Growth: Can be rapid with regular feedings. Aggressiveness: Does not bother other corals. Polyps can extend 1", and are usually out when other corals are retracted. Personal Observations Frankly, I love this coral. It is hands down, in my book anyways, the most beautiful coral so far in my reefing experience. Because it requires regular feedings, and is not photosynthetic, it has no specific lighting demands. It has been argued that it needs to be in a shady area, but this has not been my experience. I admit the polyps on mine only come out at night, but that is because I work during the day and have not had time to train them otherwise, and so I feed them at night. They do come out a little during the day when I feed my fish brine or mysis shrimp, I guess because they can "smell" it and that is the same food I feed them. With time, however, they can be made to extend during the day. When you first get this coral, it will take some time to get the polyps to come out. The method I used, and still do when I feed them, is to first turn off the power-heads that create a current around them. This is because when you first try to feed them, you don't want the food to go blowing away. Drizzle some brine or mysis shrimp, or whatever your food of choice may be, over the coral. With no current, it should float down and rest on the retracted polyps, which will coax them out. They may not come out all the way the first few times you do this, but in about a week or so they will be ready and hungry. My colony is a little bit bigger, and so it easily goes through 3 cubes of mysis or brine shrimp each feeding (I will probably start using 4, actually). I usually mix them together. I fill a small teacup with aquarium water, put 2 cubes of brine and a cube of mysis in it, let it melt, then use an eyedopper to stir it together. Then I suck some up in the eye dropper, and start to feed each polyp one by one. Each polyp must be fed, and it takes me a good 15-20 minutes. It might sound like a lot of work, but it is worth it in the end. Especially for me when at night the rest of the corals are retracted, and this most beautiful and awesome coral is out in all its glory!
