Hey, down the road, I plan to do a saltwater tank, but not sure if I want to start it off as a reef tank. I've done freshwater tanks for most of my life, so saltwater would be new territory. Question is, for somebody making their way into new territory, are reef tanks okay for beginners? And if somebody says yes, what equipment and setup would I need to take proper care of the coral? What coral are okay for beginners? And are sea fans another possibility?
