{"product_id":"guppy-grass","title":"Guppy Grass | Najas guadalupensis","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eGuppy Grass is the classic no-fuss bunch plant – brittle, branching stems of fine green foliage that grow like wildfire and shelter fry, shrimp and small fish. It floats or plants, needs no CO2 and soaks up nutrients that would otherwise feed algae. If you want fast green cover and cleaner water, this is hard to beat.\u003c\/p\u003e\n\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eNajas guadalupensis is a widespread submerged plant of ponds, lakes and slow streams across the Americas. It grows as a free-drifting or loosely rooted tangle in warm, still water. In the aquarium it is thoroughly undemanding, thriving in ordinary community conditions without special substrate or dosing.\u003c\/p\u003e\n\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eThin, wiry stems branch repeatedly and carry narrow, slightly toothed leaves, forming a soft green cloud. Left to grow it quickly fills a large volume, trailing a metre or more of tangled stems. The portion sold is a generous handful that will branch and lengthen within days; simply pinch off pieces to share or thin.\u003c\/p\u003e\n\u003ch2\u003ePlacement and Aquascaping\u003c\/h2\u003e\u003cp\u003eEndlessly flexible – let it float as a shady canopy and fry refuge, anchor it loosely in the midground to background, or wedge it among hardscape. It is brittle by nature, so handle gently; broken pieces just carry on growing. Thin it regularly so it does not shade out everything below.\u003c\/p\u003e\n\u003ch2\u003ePlanting and Propagation\u003c\/h2\u003e\u003cp\u003eNo pots or rockwool to fuss with – float it, or bury the lower ends lightly in substrate (it roots weakly). Propagation is effortless: any broken stem or side branch grows into a new plant, which is why a small portion soon becomes a jungle.\u003c\/p\u003e\n\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eGrows across low to high light, though low to moderate light is often preferred to slow it down and keep algae off the fine leaves. CO2 is not needed; a little liquid fertiliser helps in lean tanks. Keep water at 20–26 °C, pH 6.0–8.0. Growth is fast, so plan on regular thinning. It can be brittle and shed in transit, but bounces back quickly once settled.\u003c\/p\u003e\n\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eNajas guadalupensis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eGuppy Grass, Najas Grass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eThe Americas\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Height\u003c\/td\u003e\n\u003ctd\u003eTrailing to 100 cm or more\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrowth Rate\u003c\/td\u003e\n\u003ctd\u003eFast\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifficulty\u003c\/td\u003e\n\u003ctd\u003eBeginner\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlacement\u003c\/td\u003e\n\u003ctd\u003eFloating \/ Midground \/ Background\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLighting\u003c\/td\u003e\n\u003ctd\u003eLow to High\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCO2 Requirement\u003c\/td\u003e\n\u003ctd\u003eNot required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFertilisation\u003c\/td\u003e\n\u003ctd\u003eLiquid fertiliser (water column feeder)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e20–26 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e6.0–8.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003eSoft to hard, 2–18 dGH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePropagation\u003c\/td\u003e\n\u003ctd\u003eStem cuttings and fragments\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSalinity\u003c\/td\u003e\n\u003ctd\u003eNot applicable (freshwater)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable For\u003c\/td\u003e\n\u003ctd\u003eFry and shrimp tanks, breeding setups, low-tech planted tanks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eA superb plant for shrimp, livebearers, tetras, rasboras and any tank raising fry, all of which use the fine tangle as shelter and grazing surface.\u003c\/p\u003e\n\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eLarge herbivores and diggers such as goldfish, silver dollars, big cichlids and crayfish will quickly shred the soft stems.
