I have several different zoo, frogspawn, and torch frags and was wondering when do I know it's time to take off the plugs to attach them to a new home?
this can be done pretty much at any time of your choosing as long as they are not in a healing or stressed condition. The plugs are simply a temporary mounting for them although some will simply mount the entire plug and let the corals grow over them. this will not likely happen with frogspawn or torch corals though.
