What is the lowest possible water temperature for a tropical reef tank?
Right now I keep my tropical reef tank between 24 and 27 °C.

I looked into lowering it further when I planned to add a group of ventralis anthias, though Capsalid Monogeneans scrapped that plan. For now I'm looking into it to possibly lower energy cost and just in case I try the ventralis again.

I've seen post where people kept tropical reef fish in the 20 °C (68 °F) to 24 °C (75 °F) temperature window of the warm temperate zone. Fish that have a wide depth range are likely more tolerant of lower temperatures, but I could see issues with shallow water species like clownfish (A. percula), shallow water anemones (S. gigantea) and of course corals.

So, how low can you go without running into problems?
