Aquatic Plant FAQ

How much do aquatic plants cost?
Common Rotala and Anubias cost 300-1,000 yen, Bucephalandra 1,000-5,000 yen, and rare wild-collected specimens 5,000-20,000+ yen depending on species.
Can beginners grow aquatic plants?
Anubias Nana and Java Moss require no CO2 injection and grow in low light, making them ideal for beginners. Start with hardy shade-loving plants.
What equipment is needed for aquatic plants?
A tank, LED light, filter, and aqua soil are the basics. For advanced layouts, CO2 injection and high-performance lighting significantly improve growth and coloration.
What should I check when buying aquatic plants?
Ensure leaves are green and healthy, not melting or dying, and free of snails or pests. Tissue-cultured cups are pest-free and reliable.
Why do aquatic plants die?
Insufficient light, CO2, or nutrients are the main causes. Each species has different requirements, so matching the environment to your specific plants is essential.
