@sgasap22: The Australian lungfish (Neoceratodus forsteri) is considered rare and globally endangered. As of 2026, its status is defined by its extremely limited natural range and the significant threats to its long-term survival. They are among the rarest and most expensive fish in the aquarium trade. Only one licensed commercial breeder exists, and all legally sold specimens must be microchipped and registered with CITES Appendix II documentation. #AquariumHobby #rarefish #aquarium #lungfish
