Ive read online that an anemone should only be kept in a tank that is at least a year old. Is this true? I have a tank that's been set up almost 6 months with wide variety corals, live rock, inverts, and fish. I would be looking at getting an aquacultured bubble tip or mini carpet, as it seems they would be hardier than recently collected ones. Also ive been in the hobby almost 5 years, so I'm far from a beginner. Would this be okay?
