Welcome to the Great Canadian Aquarium Survey. The purpose of the survey is to get a better understanding of the freshwater plants and animals used by Canadians in their aquariums. The survey is divided into two parts. Part A should be completed by all first time users of the survey site. Part B is a shorter survey on our website to be used after every time that you add plants or animals to your aquarium – it is sort of like an aquarium logbook.
