make sure to keep any detritus from building up in the cup. the hardest thing about keeping these guys is getting enough light along the underside of the cup to keep it from dying back. for this reason the pagoda or columnar version of these are easier to keep.
that is a nice colour green!
they are tough though i had one and 99% of it died in the heater fiasco. i broke off the remaining polyps and they are still alive and starting to grow again. this is a coral that grows on the glacial time frame.
