So I've noticed that my Nerite snails have been laying eggs all over the tank... including on the shells of some of my apple snails?! Should I be worried or do anything about this? Like remove the snails? I guess I pulled a noob moved and didn't do any research on if the two types of snails are even allowed to be together. Both types of snails have been in the tank together for over a year now. These eggs are the first time I realized there might be an issue.
