Given the interest in Malaysian snails, I'd really like to know what snails are worth keeping as I'm a newbie when it comes to snails. As there isn't much literature which explains aquatic snails in detail in my area, I'd very much appreciate it if you folks could point out any website or even give me some pointers on snails worth having in the aquarium.
