Beautiful encounter with this rare specimen: Fish-angel dwarf blue of Mauritius. It is a very rare fish that was until now only referenced in Mauritius, Réunion and Aldabra. He is also present in Mayotte. It is a fish as beautiful as it is rare. Living in great depth (here at 80 meters) it is highly sought after aquarists whose price of an individual may have arrived at $ 20,000. But whatever its price, its place is certainly not in a cooler aquarium but in the twilight of the Twilight Zone, its natural habitat. I'm really happy and I feel privileged to observe it at home: in the mesophotic zone.
