Yeah, just don't overfeed your fish and you won't have a snail problem. I got some snails with some plants one time. I saw one pond snail right after I put the plants in, but it was 2 weeks before I also saw ramshorn snails. I think my bettas ate the ramshorns, though, because I only ever saw really small ones and I haven't seen any in a while. And I only have 2 pond snails in that tank. I only feed each betta 3 pellets at each feeding and I make sure they eat one before I drop the other in, so there is almost never any leftover food.
