As a rule Gonipora lobata (the mot commonly imported "flower pot coral") is nearly impossible to keep. IMO G. stokesi as well as many branching species, and many Alvepora sp.are pretty easy to keep given the correct enviornments. Easier than many sps type corals. G. lobata and G. stokesi can be very difficult to tell apart. So can Acropora species for that matter. If you don't know what you are buying, cant tell what a healthy specimen looks like, and can't trust who you are buying it from well then you are definately taking your chances with any coral!!! Thats an accurate statement. Maybe someday we will have a LFS around St. Louis that isn't trying to make a quick buck and that you can trust when they tell you that a coral is easy to keep. Maybe around around march 1st would be nice.
