These fish are found over a good size range (South Africa to southern Japan), however, they tend to be found in cool water (62-65F), there are small sub-populations that live in slightly warmer, but not tropical. This population from the Philippines (Cebu island) is more tolerant of warmer water (low 70s) -cooler than our reeftanks, but not too far off. So they appear at least better suited for a try in the home aquarium.
I'm hoping we can learn something from Cranberry's fishes, as these fish are coming in more frequently, and just drop w/in a few months, regardless of how well they are feeding
To my knowledge they dont head to warm waters to breed, they do everything at cooler temps and again this Cebu population appears to be a warmer tolerant fish. Lets see what happens
