I am in need of at least 50 P. canaliculatas for my scientific research paper for my Majors Biology course. I am testing the allelopathic effects of Elodea canadensis on P. canaliculatas. I've been looking for these snails for hours now and am having no luck. I won't need them for a while, but I wanted to go ahead and start looking. Now I'm thinking I may have to choose a species of snail that will be easier to obtain. I would even be willing to breed the amount I need if I can get them in time. Any help would be much appreciated.
