Forgiving enough for hobbyists with one tank of experience. Watch lighting and nutrient levels for best growth.
CO2 & Fertilization
CO2 is optional. Growth improves with supplementation, but the plant survives and stays presentable without it.
Tank Size & Setup
Works in tanks 10 gallons and up. Match the plant size to your tank depth for the cleanest aquascape.
Aquascaping & Placement
Position to suit your aquascape — most placements work as long as light reaches the leaves.
Tank-Mate Compatibility
Compatible with the full range of community-tank species — tetras, rasboras, livebearers, corydoras, and most other peaceful freshwater fish do not damage the foliage.
Common Care Issues
Slow initial growth
Most aquarium plants pause for 2-4 weeks after planting while they convert from their nursery-grown emersed form to fully submerged growth. New leaves that emerge underwater will look thinner and slightly different — this is the plant adapting, not a problem.
