something not discussed enough in this thread is stocking. It’s nearly impossible to find small enough wild caught specimens to add together. I’ve got a pair of coral beauties, a pair of regals, a pair of marine bettas (not pictured) a pair of venustus (not pictured), a single goldflake and majestic. They’re housed with several wild caught quarantined fish including a Midas Benny, a copperband and also “wild” live rock (again properly qt’d). IMO adding them together at a small size has been critical to their success.
