Common Name: Crypt Spiralis (also sold under the name Crypt Retrospiralis) Flag: this listing's title says "Spiralis" but its original body text described the plant throughout as "Crypt Retrospiralis" — a related but distinct Cryptocoryne species. Since it's unclear which name is correct for this specific stock, both names are noted here; please verify against current product photos which species this actually is. A beautiful mid- or background Crypt that has been a popular aquarium plant for generations — relatively easy to grow, with a loose corkscrew shape to its long, reed-like, hammer-textured leaves that make an intriguing backdrop or accent. Skill Level Easy CO2 Not Required Requires Aqua Soil Recommended — feeds through the roots in good aquarium substrate Type Rooted (Crypt) Max Height 10-24" Placement Midground / Background Light Level Moderate (approx. 40-70 PAR) — higher light brings out more color; will melt under overly strong light Origin India, China, Thailand Other Family: Araceae. pH 6.5-7.5. Easier to grow submersed but can also grow emersed, producing pink/purple flowers above water. Propagates via runners. Care & Planting: Remove the cotton surrounding the roots and plant into quality substrate, or attach to hardscape with thread. Cryptocoryne prefer not to be moved once planted — avoid relocating them if possible. A note on "crypt melt": Cryptocoryne are well known for shedding their leaves after being moved, replanted, or exposed to a sudden change in water parameters. This is normal — new, better-adapted leaves typically regrow within a few weeks once the plant settles in. Don't panic if it happens; just maintain stable conditions and give it time to recover.
