"To be honest, they are the biggest goldfish I've ever seen," said Saint Johner Riley Keenan, who estimates some fish are 10 inches, or about 25 centimetres, long. "it's just a weird thing to see." "I've swam with fish before," said swimmer Bonnie Ferguson."But goldfish? Not so much." How'd they get there? The goldfish didn't get to the Cuts on their own. The best theory is that "they were someone's pet that they released," said Graeme Stewart Robertson, executive director of the Atlantic Coastal Action Program in Saint John.
