Agressive feeding fish

Kasandra Munroe, an employee at Creatures Pet Store in Victoria, said the fish are fairly popular.

"If someone likes an aggressive feeding fish they're gonna want a piranha," Munroe said, adding that the store has sold about 60 of them in the past year.

Despite horror movie lore, Munroe said the piranha was unlikely to be a problem for anyone spending time at the lake. She said they would only be likely to attack large prey if they were starving and swimming as part of a larger school of piranhas.
