Someone stole 15 of the 21 adult moi from an outdoor display tank at the Waikiki Aquarium this past weekend, the aquarium reported today. The fish were valued at an estimated $1,500.

It appears the theft happened after hours on Friday, the aquarium said. Someone cut the netting that covered the top of the tank.

Moi, also known as Pacific Threadfin, is found only in Hawaiian waters. The aquarium moi were a gift from Anuenue Fisheries, which is no longer in operation.

The aquarium filed a police report. Anyone with information about this case is asked to all police.
