A dependable midground plant for low-tech tanks.\u003c\/p\u003e\u003ch2\u003eNatural Habitat\u003c\/h2\u003e\u003cp\u003eFound in streams, rivers and marshes across Sri Lanka, growing both submersed and emersed as water levels shift with the seasons. Give it a mature, stable aquarium with nutrient-rich substrate and gentle flow, and let it settle in one spot.\u003c\/p\u003e\u003ch2\u003eAppearance\u003c\/h2\u003e\u003cp\u003eNarrow, undulate (wavy-margined) leaves in olive-green to brown, often with a darker patterned upper surface and reddish underside, reaching 15–25 cm tall. Supplied as a tissue-culture cup of small plantlets that need a few months to reach size. Post-planting melt of old leaves is normal - regrowth comes quickly from the roots.\u003c\/p\u003e\u003ch2\u003ePlacement and Aquascaping\u003c\/h2\u003e\u003cp\u003eA midground plant, or background in nano tanks. Plant in loose groups 5–8 cm apart; its wavy, upright leaves make a fine transition between low foreground plants and taller background stems.\u003c\/p\u003e\u003ch2\u003ePlanting and Propagation\u003c\/h2\u003e\u003cp\u003eRinse away the nutrient gel, divide into individual plantlets and plant with crowns above the substrate. Propagates readily by runners; separate and replant plantlets once they carry a few leaves.\u003c\/p\u003e\u003ch2\u003eCare Requirements\u003c\/h2\u003e\u003cp\u003eLow to moderate light, no CO2 needed, root tabs or a nutrient substrate for the roots. Water of 22–28 °C, pH 6.0–7.5, soft to moderately hard. Growth is slow to moderate; stronger light and CO2 deepen the brown tones but are entirely optional.\u003c\/p\u003e\u003ch2\u003eSpecies Information\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific Name\u003c\/td\u003e\n\u003ctd\u003eCryptocoryne undulata\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Name\u003c\/td\u003e\n\u003ctd\u003eUndulate Cryptocoryne\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eSri Lanka\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Height\u003c\/td\u003e\n\u003ctd\u003e15–25 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGrowth Rate\u003c\/td\u003e\n\u003ctd\u003eSlow\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\u003eMidground\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLighting\u003c\/td\u003e\n\u003ctd\u003eLow\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\u003eRoot tabs (heavy root feeder)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Temperature\u003c\/td\u003e\n\u003ctd\u003e22–28 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Range\u003c\/td\u003e\n\u003ctd\u003e6.0–7.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGH Range\u003c\/td\u003e\n\u003ctd\u003e3–15 °dGH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePropagation\u003c\/td\u003e\n\u003ctd\u003eRunners\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\u003eCommunity tanks, low-tech setups, beginners\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSuitable Tank Mates\u003c\/h2\u003e\u003cp\u003eTetras, rasboras, corydoras, gouramis, shrimp and snails all coexist happily with crypts.\u003c\/p\u003e\u003ch2\u003eAvoid Keeping With\u003c\/h2\u003e\u003cp\u003eGoldfish, silver dollars, uaru and large digging cichlids.
