I found an article that said lighting can be tricky with them, some like it hot, and some don't. Do I keep him in an area for how long before I try another area? 3 days, 3 weeks? I don't want to rush it, but I want the right location. We are going back to 4 vho on my 72 gallon next week, so I can start hard corals again. Will he go at the bottom then?
