Its stems branch constantly along their length, carrying thin, translucent leaves barely a millimeter or two wide, and it grows as readily floating loose at the surface as rooted into the substrate. In the Botanical Method Aquarium, this fine branching structure provides fry and shrimplets refuge and grazing surface. As a water column floating plant, mild water column fertilization is recommended.\u003c\/p\u003e\n\u003ch4\u003eEssential Details\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCare Level:\u003c\/strong\u003e Easy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Habit:\u003c\/strong\u003e Fast, brittle stems can fragment easily\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight:\u003c\/strong\u003e Low to Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCO2:\u003c\/strong\u003e Not Necessary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePropagation:\u003c\/strong\u003e Stem fragmentation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTint Tolerance:\u003c\/strong\u003e Low to High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHabitat Location:\u003c\/strong\u003e Freshwater ponds, ditches, and low-flow streams from Canada through Central and South America\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimal For:\u003c\/strong\u003e Betta fish, shrimp, guppies, killifish, and other species being bred or raised where fry need dense cover and a grazing surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse with Caution:\u003c\/strong\u003e Rinse before introducing; may carry beneficial hitchhiking snails, snail eggs, or duckweed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize Range:\u003c\/strong\u003e Leaves roughly 1 to 3 cm long and 1 to 2 mm wide; stems reach 2 to 3 feet if left untrimmed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantities:\u003c\/strong\u003e Sold as a loose bunch of 7 to 10 stems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eGuppy Grass for Planted Aquariums \u0026amp; Blackwater Biotopes\u003c\/h4\u003e\n\u003cp\u003ePeriphyton colonizes every inch of Guppy Grass, which, left unpruned, can form dense networks, providing supplemental nutrition and areas of refuge for fry and shrimp in the Botanical Method Aquarium. This aquatic plant is best used in a breeding aquarium, as its fast growth provides newly hatched fry food and cover.\u003c\/p\u003e\n\u003cp\u003eGuppy Grass feeds from the water column rather than the substrate, pulling nitrogen, micro-, and macronutrients directly from the water. Its quick uptake is also how it can help outcompete algae for nutrients. As a free-floating aquatic plant, its growth is not really dependent on light reaching the sediment; therefore, tint has little bearing on how the plant grows, and it does well in darkly tinted water from leaf litter and seed pods. We recommend keeping a clump in all of your ecosystems to help uptake nutrients, pruning back excess growth each week during your water exchanges.\u003c\/p\u003e\n\u003cp\u003eFragmentation is how Guppy Grass propagates. Its stems break easily, and any loose piece left behind can grow into a new bunch. We keep ours floating in most of our ecosystems, where it sits close to the light and grows fastest, and thin it regularly so the plants rooted below still get the light they need.\u003c\/p\u003e\n\u003ch4\u003eBeneath the Leaves: \u003cem\u003eNajas guadalupensis\u003c\/em\u003e in the Wild\u003c\/h4\u003e\n\u003cp\u003e\u003cem\u003eNajas guadalupensis\u003c\/em\u003e grows in shallow ponds, ditches, and low-flow streams throughout the Americas. It's native habitat has silty substrates, where it's roots can grow into readily. \u003cmeta charset=\"utf-8\"\u003eGuppy Grass is an annual plant, sprouting from deeply pitted seeds in the spring, growing vigorously through summer and early fall, then going to seed again. The bank of seeds these plants produce is equipped to survive the cold months of winter, before sprouting again from the sediment.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eInvertebrates colonize the densely growing stems and feed the fish, amphibians, and wading birds of the shallow waters of its natural habitat. Migrating mallards, pintails, and lesser scaup graze on the stems, leaves, and seeds. Seeds that survive the trip through a bird's gut germinate in new water bodies the birds migrate to. This dispersal route is documented across the genus, and it is part of how a plant with no runners and no rhizomes reached the range it holds today.\u003c\/p\u003e\n\u003cp\u003eWhere a botanical contributes as it breaks down, an aquatic plant is living and contributes as it grows.
