I have a 29 gallon heavily planted tank. I'd like to get a snail (or maybe 2) for this tank. I'm a little picky though. I'm not looking for a large snail, preferably a smaller type, one that won't eat my aquarium plants and one that won't breed out of control (or at all would be great!). I was thinking a nerite or two, but please make any suggestions. I'm pretty new to snail keeping and don't have any at the moment so any help is GREATLY appreciated!
