I need a few plants for a 20gal. tank and can't find much at Petco or PetsMart. Looking for multiple varieties short and tall and something that does well as a floating plant to provide some cover for shy tetra species. I've been to multiple branches of the above stores and just don't care for the selection...which is always minimal.

Are there any Atlanta shops that carry more than the chain operations? Yes I know, I just missed the Spring auction. :)

Thanks.
