{"product_id":"climbing-swamp-fern","title":"Climbing Swamp Fern","description":"\u003cp\u003eKelakai is the Indonesian name for \u003cem\u003e(Stenochlaena palustris)\u003c\/em\u003e, a climbing fern native from tropical Asia to the western Pacific. In Borneo and Sumatra, it scrambles through swamp forest, forest edges, and the margins of blackwater streams. Ours is imported from Indonesia, within its native range. The fronds are once-pinnate, with long, narrow leaflets edged in fine teeth. Dried, they are dark tan to olive-brown and 20–50+ cm (8–20+ in) long, with a slightly papery, fibrous texture. In the aquarium they release medium tannins over 3–6 weeks for a warm amber tone. The fine leaflets build biofilm that shrimp and small fish graze. Draped over roots or tucked between stones, the fronds form a loose tangle like the edge of a peat swamp. They are a native fit for Bornean and Sumatran biotopes.\u003c\/p\u003e\n\u003ch3\u003eHabitat Snapshot\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong1\u003eTannin Character: \u003c\/strong1\u003eMedium · \u003cstrong1\u003eWater Tone: \u003c\/strong1\u003eWarm amber · \u003cstrong1\u003eHabitat Origin: \u003c\/strong1\u003eImported from Indonesia (native range: tropical Asia to W.

Boil for at least 25 minutes, then let the fronds cool in the water. Soak in warm water for 30–60 minutes to help them sink; large fronds may need longer. Trim to fit if needed. Drape over roots, tuck between hardscape, or layer under larger leaves. Use 3–5 fronds per 10 gal (38 L). \u003cem\u003ePairing:\u003c\/em\u003e Layer under Macaranga Leaves for a deeper-toned Bornean litter bed.\u003c\/p\u003e\n\u003ch3\u003eBest For\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003eBorneo and Sumatra peat swamp biotopes, Sabangau-inspired builds, wild bettas such as \u003cem\u003eBetta hendra\u003c\/em\u003e, and \u003cem\u003eParosphromenus\u003c\/em\u003e (licorice gourami) tanks.\u003c\/p\u003e\n\n\u003cp class=\"product-notice\"\u003eNot for human consumption.
