The main issue is a lot of Tilefish species aren't suitable for the average Reef Tank. In the wild, they're all found in deeper waters in flat terrain where they like to make burrows similar to a jawfish and usually live in pairs. Bright lighting, high flow (like in an SPS environment), and lots of rock structures aren't their thing and usually why they stress out a lot. They're also just very skiddish and jumpy in nature, especially the Purple tiles.
Ironically Elliot Lim from Marine Collectors says that in his experience, the Oreni is the most calm of all the species he's worked with which is surprising but nice to hear the most expensive species for once is the LEAST likely to Carpet surf lol
