Slender Pond Weed (Potamogeton Gayi) - Christel Kasselmann, in her aquarium plant bible, calls this an ideal aquarium plant (that has, unfortunately, been displaced in the hobby by more attractive alternatives). Once established, it can spread quickly, by sending out runners, and may have to be thinned out from time to time. Accepts a wide range of water parameters and light conditions. -  7+ rooted plants
