The DEBATE is so amusing especially the frank outburst statement about fishes found in coral reefs are deemed 'reef-safe'. But 100% of all marine fishes (reef-safe or not) captured for the aquarium trade are found in coral reefs leh except aquacultured ones. Butterflyfishes/Angels in the wild got plenty of SPSes/LPSes polyps to choose & 'whack'. In a closed tanky environment, they have only Hobson Choice. Cannot 'Hiam'.
