So I have my one beautiful purple mystery snail, Happy the Fearless. Today I discovered a clutch of eggs under the lid. Happy has been n the tank for 6-8 weeks at least, maybe 12? I take this as a sign that Happy is... Happy. Questions: 1: does this mean Happy is female? 2. Am I safe to assume the eggs are not fertilized since I only have one? Can they store sperm the way live bearers can? I was just going to leave it for now. Thanks.
