Two casinos at Gulfstream Park had to be closed after a 13,000-gallon aquarium sprang a leak.

A seam in the aquarium in the second-floor casino cracked open early Sunday.

Director of gaming Mike Couch tells The Miami Herald that it wasn't clear when the water damage to the first- and second-floor casinos would be cleaned up. Gulfstream's shops, dining rooms and simulcast area remain open.

Couch says casino employees raced to plug the leak with towels and supplies from the bar area.

About 3,000 gallons of water remained in the saltwater aquarium. Couch says that was enough to keep more than a dozen fish safe and swimming until they could be moved to another aquarium. The fish include sharks, a lion fish, a puffer fish and various tropical species.
