Is there any benefit at all to having them in a planted tank? I got some free gravel from a guy that is supposedly good for planted tanks. There is a bunch of snails with it though. So should I leave the snails (looks like there are a ton of tiny ones)? I've heard they are very hard to get rid of once you have them. I've never had a single snail in any of my tanks in the past. I guess it doesn't really bother me much if they aren't a problem. If I do decide to try to get rid of them...I'm thinking that a couple of snail eating fish seem like a logical solution. Any suggestions for smaller fish that eat snails? The only fish in there are a small pleco and an African Brown Knife.
