Cryptocoryne Willisii is a less common Crypt with bright green, grass-like leaves — similar in appearance to Cryptocoryne lucens. Like other Crypts, it grows at a moderate rate and can be kept submerged or emersed. Skill Level Easy CO2 Not Required (recommended for faster growth) Requires Aqua Soil Not required, but recommended Type Rooted Max Height 2-4" Placement Foreground Light Level Low to Medium (approx. 20-50 PAR) Origin Sri Lanka Other Note: correcting a data error found on this listing, which had this species mislabeled as endemic to Borneo — Cryptocoryne willisii is native to Sri Lanka. Care & Planting: Remove from the pot and root wool before planting into quality substrate. Crypts dislike being moved once established — pick a spot and leave it. To propagate, cut off new plantlets growing from the mother rhizome. 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.
