on this day in 1935, cane toads were introduced into Queensland in order to control the cane beetle that were wreaking havoc in the sugar cane plantations. The toads proved ineffective as a biological control method against the cane beetle. They have instead, become a real pest to the environment, spreading across state borders and a real danger to your pets if they try to eat these critters.
In the aquarium industry, we need to be more responsible than to release non-native fishes into the environment.
