So ... I finally got snails - not by choice however. I know they come from plants, which i find rather strange considering i haven't bought any new ones in awhile. I was really digging up the gravel today to do some replanting and put some laterite in - they didn't come from that did they? I do seem to recall seeing things before that I thought were plant spores so I chucked them, or dropped them back in the tank.
I'm not particularly interested in getting rid of them and I could really use the help with algae. So, my question is; what am I looking for to make sure they don't become a nuisance to my betta? I know they can cause disease, and one thing to watch out for is a spike in ammonia but other than that what else?
