Some of these species are hard-ish to get in aquariums like lookdown (at least for New England aquarium) but that might because they aren’t local. While I like this aquarium, I don’t like the lack of any signage of some sorts. Also, who manages this tank?
@MOG2012 Did some looking online and I couldn't find much, though the tank is likely managed by aquarium staff at the palace, though I am not sure if they are hired from a different place. Surprised that lookdown would be tricky to get, they are quite common in many aquariums with larger tanks.
