The Favia or Favites coral are all easier to care for, great looking corals. All of the Favia, Favities corals are excellent LPS corals for beginner reefers. Some common names these corals are known as are the Pineapple Coral, Moon Coral, Brain Coral, Star Coral, Honeycomb Coral, Worm Coral and other names I can't think of right now. Colors seen include green's, cream, yellow's, orange, blue's, reds, and pink tones. Often times there will be mixes of the colors with the "walls" being one color, and the calices "centers" being another, making for very attractive reef tank additions. They are the most common and prolific coral in the world. Many of the colors cannot even be seen under normal lighting, but placed under aquarium actinic lighting, wow, there they are! Favites and Favia, share most of the same common names, they are very difficult to tell apart.
Difficulty Easy to care for.
Aggressiveness The Favia coral has potent sweeper tentacles that it will extend out well past its base, keeping other corals from growing too close and will sting anything within reach with its nematocysts. Because of this, you should take care to ensure that your coral has enough room both now and in the future, once the corals in your tank have begun to fill-in the available space.
Like most large polyp stony corals, it requires a moderate water flow. .
Requires moderate lighting levels (from PAR 100-250).T5's, Metal Halides, or LED's can all grow a healthy Favia coral when the proper PAR levels are provided. We recommend a 14-20K color spectrum for best coloration. If it will be exposed to brighter lighting it needs to be kept within a shaded rock area to cut back the lighting levels.
A mature, well-fed live rock/reef environment is what is needed, along with some fish for organic matter production, and dissolved organics. As a general rule, caution should be used when mixing leather coral. Large polyp stony corals protect themselves by wielding their sweeper tentacles. Many of the leather coral species, by comparison produce and release toxic chemicals, called terpenes, into the water to stunt the growth of other species.
Diet and Feeding
It is not necessary to feed a Favia coral, although they are capable of eating fairly large (by coral standards) meaty foods. The fact that they are biologically able to consume rather large, meaty meals, suggests to me that feeding should be strongly encouraged. However Favia could be kept successfully in a reef tank without any feeding at all, as long as adequate lighting is provided, because their symbiotic zooxanthellae will sustain them. If you want to feed, they will eat mysis, fortified brine shrimp, rotifers, Cyclopeeze and other similarly sized meaty foods. Larger pieces than a typical mysis is not digestible, and although the animal "accepts" it, it will regurgitate it up later in the night.
