i am thinking about setting up a 10 gal with a couple fiddler crabs. i want to fill it halfway then put floating plants and rocks cuz they need to get out of the water, but what kind of filter should i use? would an undergravel filter be the best bet? i dont really have that much to spend or i'd be buying a larger tank of course any help would be great thanks
