I have been culturing this Rainbow Goni since 2013. It has been rock solid. No matter what conditions my tanks are in it has always had great color and growth. This is a short tentacle Gonipora, not even sure if it is even a goniopora. At times it will extended a couple tentacles longer but not all the time and is usually only has about a 1/2 reach.
