Emma Marsh, who lives in Brisbane, Australia, noticed that her goldfish, Conquer, had begun to choke after he accidentally swallowed a rather large, black pebble from his tank.
No matter how much he tried to spit the pebble back up, Conquer was unable to due to the stone's size. If Marsh hadn't taken him to Brisbane Bird and Exotics Veterinary Services, he would have eventually died from starvation due to the pebble blocking his airway.
As soon as Conquer arrived at Brisbane Bird and Exotics, veterinarians got to work. In order to remove the stone stuck in his throat, vets first dripped an anesthetic into the same water the goldfish was brought in with.
