In the video, released on Oct. 23, Tropical Discovery dive specialists Alex and Tim got into the spooky spirit as they carved fish shapes into pumpkins. The footage showed fish swimming up to the gourds as the divers worked.

According to the zoo, underwater pumpkin carving, while festive, also provides nutrition for fish at the zoo’s Tropical Discovery enclosure.

“It’s October, and that means it’s time for festive enrichment!” Denver Zoo said. “While festive for humans, this is also great for the fish, who enjoy this activity as our predators might enjoy a carcass feeding.”
