Despite some reports that merely taking a scissors and snipping of the sweepers is an effective way to get rid of them, it has been my experience that this is a temporary and fruitless endeavor. More sweepers will be formed in their place, and consistent snipping of living tissue always poses a risk of losing the coral to a resultant infection. Therefore, I feel the best solution is to place any Euphyllia species well out of contact range with any other corals. It may be noted, though, that with the exception of E. glabrascen s, all Euphyllia species may be placed near each other, as they do not seem to have any negative interactions between species. Captive reproduction of most Euphyllia species is by budding of daughter colonies around the base of the parent or by separation of a colony from the living tissue edge around the septa.
Sexual reproduction occurs in the wild, and has been documented in captivity, as well.
My first stony coral, as with many people, was a hammer coral. It has survived through many moves, sometimes awful tank conditions, and continues to grow and prosper. Thus, it can be said that this is a fairly hardy coral. Most Euphyllia species are fairly light tolerant and adapt to most lighting regimes. I have found that while they prefer bright light, excessively intense light can cause a marked retraction of the polyps.
