British Columbia conservation officers say two piranhas found in a Vancouver Island lake were likely unwanted pets.

One red-bellied piranha was reeled in by an angler at Westwood Lake in Nanaimo last week.

Another was caught in the same lake during the summer.

The provincial Conservation Officer Service says in a Facebook post that the tropical fish with sharp teeth can't survive winter climates.

The service says introducing aquatic invasive species can have harmful impacts, including threatening native fish, ecosystems and other species.

It adds that it's illegal and a conviction for a first offence could result in a fine of up to $100,000 and a prison term of up to one year.

This report by The Canadian Press was first published Sept. 30, 2019.

By the look of it, that thing was a pretty healthy specimen .. I hope that that is 20 cm and not 20 inches .. although Wikipedia does say that they can get that big, at which point they can weigh up to 4 kg (almost 9 lbs).

Look out salmonids!
