Of the two types of flowerpot corals, Alveopora are generally considered "easier" to keep alive. Well over 90% of all sold Gon. are dead within 3 months. They're beautiful, but species that are so hard to keep should be left in the ocean (IMHO), except for culture by experienced reefers. Unfortunately, they are among the cheapest to import (re: highest profit margins for the LFS) so it is also one of the most common corals up for sale to the unsuspecting public
who are attracted to the motion & beauty of the waving arms. Many unscrupulous LFS will not mention the dismal success rate & countless reefers try more than once to keep these creatures. (Guilty as charged
)
