I was looking in my tank and noticed in a hole in one of my rocks two bundles of what looks like eggs and a hermit crab under them what looks like guarding them. I also have snails that have been breeding and have noticed some baby snails so it may also be snail eggs, or not eggs at all. I have no idea to be honest. I have an 8 gallon nano reef and am learning as I go but have had the tank for about 2 years and never saw these before. Any help is appreciated. Thanks!
