15 Recommended Aquatic Plants

1. Anubias Nana - **Difficulty**: 1/5 / **Price**: 500-1,500 yen / **CO2**: Not required / **Light**: Low-Medium

Pros: The ultimate beginner aquatic plant. Just attach it to driftwood or rocks. Survives in low light. Slow growth means no trimming needed. Cons: Slow growth makes leaves prone to algae buildup. Care tips: Attach to driftwood with thread or glue. Add Amano shrimp or Otocinclus for algae control.

Frequently Asked Questions (FAQ)

Q. Can I have a planted tank without CO2 injection? A. Yes. Anubias, Java Fern, Willow Moss, Hornwort, and others grow perfectly well without CO2.

Q. Why are my aquatic plants melting? A. The main causes are sudden environmental changes (water chemistry, light level, temperature), nutrient deficiency, and CO2 deficiency. Cryptocoryne is prone to melting when first introduced, but will recover if the roots are alive.

Q. Do I need fertilizer? A. Not initially if you use aquatic soil substrate. Add liquid or solid fertilizer after a few months if growth slows.

Q. How do I deal with algae? A. The basics are adding Amano shrimp and Otocinclus, managing lighting duration (under 8 hours), and performing proper water changes.
