I have never had real plants in my tank before and I am trying it out today bought 2 plants from my lfs and forgot to ask someone about snails. I have the 2 plants in my 5 gal hex tank and i noticed there was a small snail in was in my tank, are they good for plants or bad. I have snails in my other tanks but I think my fish are eating them so I dont care if they are in my tanks with the fish. Was wondering if I should worry?
