Im thinking about getting a snail or two but im under the impression that they mainly eat algae?
Yes?
No?
...Yes and no?
none of my tanks have algae at all, ever. (Is that normal? Or does it have to do with the sunlight exposure) Ive only ever had algae in the 3 gallon in my old house like...maybe seven years ago

So, do i have to buy food for them or do they just eat fishie poopie D: and other stuff they happen to find. And should i get some live plants for them, i probably will anyways, snail or no snail, but what kind should i get?
I had snails before (3gal, old house, 7years) and they seemed pretty happy. Hopefully i can have it happen again :D
