Animals of different ages were kept in separate large holding tanks filled with Cu2+-free water (18–20°C). Pond snail is a hermaphrodite species that can self- and cross-fertilize (mixed mating system) with a preference for outcrossing and that experiences low inbreeding depression. They won’t breed if it is too low for them. Hence, it plays a crucial role in the functioning and health of many aquatic ecosystems (Segner et al., 2003). However, I would recommend doing that in the snails’ tank only! They are living things, after all. Brain Res.
