[i have crabs]

i herd a someone from the zoo today on the radio and it seems like they have no clue what happened wich i guess isnt news but when asked if they had any staff with experience or expertice on keeping rays or animals like them the zoo guy completly dodged the question wich seemed like they have no qualified person to me wich is a little unresponsible if true, hope its not.
i do wish we could see what type of equipment is used 40 something rays seems like way to many i seen the tank with 18 and thought that was enough, i also wonder what tests they do and how they test them
