Sorry...guadalupensis only has 1 L.Remember what I said about the world wide web. Type in "carpet plants" or " floating plants" or whatever category and always type "for aquariums" after you put in the category. You will have s a better chance of finding what you're looking for. The botanical name for guppy grass ls Najas guadallupensis and other common names other than guppy grass, najas grass, and common water nymph.
