intereting i found this on euphyllias,
Stocking an aquarium store with quality corals is becoming a challenge. Obvious statement, but perhaps this is useful for those of you who are interested in finding coral species to propagate. Euphyllia species: Hammer, Frogspawn, and Torch corals, have long been among the most popular corals for reef aquaria. They are durable, beautiful, and surprisingly easy to propagate. Among stony corals, they are always among the first stony corals suggested for a beginning hobbyist and indeed few reading this board have not tried keeping any of these species.
Unfortunately, because of their high desirability, Euphyllia are also a target for over-collection. At current, their collection is limited to the point where quotas amongst collectors, wholesalers and retailers are enforced. These corals have been targeted for sustainability studies and their collection in certain collection regions like Indonesia are monitored and controlled quite closely. I am not certain but have heard that importation into the European Union of Euphyllia has been banned for several years and would anticipate that in a short number of years they may be excluded from the North American trade as well. I have no idea of the relative success of these protection programs and have to say that if it works, more power to all of those involved to prevent these gorgeous animals from disappearing from the reefs.
