If you thought the fad of swallowing goldfish went out with the 1920s, you may not be keeping up with current Internet sensations.

Youthful—and, sometimes, not so youthful—Internet users across the world have flooded the Web with videos of themselves and other swallowing goldfish, minnows, beta fish, guppies and just about anything else that swims. A YouTube search for goldfish swallowing videos turned up about 1,200 videos as of November 2012, and a similar Google search returned more than 17,600 relevant pages.

Entire websites, in fact, now cater to people who either enjoy seeing others swallow live fish or like to gulp the creatures themselves. On GoldfishSwallowing.com, for example, members can watch more than 300 videos of sexy girls seductively slurping down live fish of all types. For a small monthly fee, members can email goldfish swallowing models, donate favorite pets to be swallowed and even submit special requests to models who will swallow almost any kind of live or inanimate prey.

At TheVoreStore.com, users can download individual videos of girls swallowing live fish that range from goldfish to small sharks. For as little as five dollars, website users can download a custom-made video that shows a model playing with, taunting and ultimately swallowing live prey. The website also features DVDs, autographed items from swallowing models and a section that showcases men swallowing live fish.

ArianaGirls.com, another website dedicated to goldfish swallowing, touts its collection as the "indisputably largest online archive of real life Swallowing and Vore videos." On that site, members can watch hundreds of videos of girls swallowing live fish, see videos of girls eating food, see girls swallow non-food items and browse various adult entertainment options.

Even the most mainstream online retailers cater to the goldfish swallowing niche. On Amazon, for example, shoppers can buy a 52-minute DVD from GoldfishSwallowing.com that includes nearly two dozen individual goldfish swallowing videos. The site also offers several goldfish swallowing videos available for purchase, streaming or instant download.

Even though the goldfish swallowing fad may have reached its heyday nearly a century ago, there are certainly signs that the notion of swallowing live fish is far from dead. Many of the goldfish swallowing websites offer advice on how to get started with swallowing live fish, and some include forums in which members encourage each other to explore their voracious interests.

Whether it lives on as a fad, a fascination or a fetish, there is no doubt that goldfish swallowing is here to stay.
