Cryptocoryne Tropica

Overview

Cryptocoryne wendtii 'Tropica' is a popular wendtii form with compact, strongly crinkled leaves in green-brown tones. It is hardy, grows in low light and makes neat clumps in the foreground to midground.

Water Parameters

• Temperature: 22–28°C (72–82°F)
• pH: 6.0–8.0
• Hardness: 3–15 dGH

Lighting, CO₂ & Nutrients

• Light: Low to medium
• CO₂: Not needed
• Nutrients: Heavy root feeder — use a nutrient-rich substrate or root tabs every 2–3 months

Placement & Growth

• Position: Foreground to midground
• Size: About 10–15 cm
• Growth rate: Slow to moderate
• Difficulty: Intermediate

Planting & Care

• Plant in the substrate with the crown (where leaves meet roots) just at the surface
• Place root tabs nearby; Crypts take most nutrients through their roots
• Once planted, avoid moving it — it settles and spreads better undisturbed

Propagation

• Sends runners under the substrate; new plants appear nearby and can be separated once they have roots

Common Issues

• "Crypt melt": leaves may dissolve after planting or a big change in water — this is normal; keep the roots in place and new leaves return within weeks
• Avoid sudden large changes in temperature or water parameters
