I really don’t understand. Maybe because I just have soft corals right now but I don’t understand what makes certain corals more difficult than another coral (softies are easier than LPS, LPS are easier than SPS, etc). I don’t do anything for those corals besides providing their lighting, flow, and parameter needs and they grow. And I’m not talking about those corals that have high feeding or parameter demand or have low survival rate. Is there something about LPS and SPS that makes it any more difficult than taking care of my softies if I provide them the right conditions?
