So I got hitch hikers, no surprise. Was gonna be a live and let live unless they become a problem. When I first noticed them there were 4. So my tank is going trough the tedium of a fish in cycle and figured I must be crushing them or something when I do my water changes. No real loss as they are common pond snails. I seem to be down to one after two weeks. I saw eggs, Lots of them. I do not know if I'm still in for an infestation to occur. What's the average time it takes from egg to "that's no doubt a snail" and how long do those things live anyway? It's more of a curiosity than anything
