Anacharis Elodea Densa: Fast-Growing Oxygen Machine for Your Tank
Looking for an aquarium plant that’s easy to grow, helps fight algae, and keeps your fish healthy? Meet Anacharis (Elodea Densa)—one of the best beginner-friendly aquatic plants out there.
What Is Anacharis?
Anacharis, also known as Elodea Densa, is a fast-growing freshwater plant native to North and South America. It’s a stem plant with long, bright green leaves that grow in whorls around a central stalk. In the right conditions, this plant can grow several inches per week!
Why We Call It an “Oxygen Machine”
Anacharis isn't just pretty—it works overtime for your tank. During the day, it photosynthesizes and pumps oxygen directly into the water. You’ll often see tiny bubbles on its leaves, a sign that it's actively enriching your tank's oxygen levels. This makes it perfect for tanks with fish that love clean, well-oxygenated water like tetras, guppies, and goldfish.

How to Plant Anacharis
You’ve got options:
-
Root it in the substrate for a classic stem plant look.
-
Let it float to create natural shade and surface cover.
-
Bundle it with a plant weight for a loose, jungle-style scape.
It does best in gravel or sand, under moderate to high light, and with a liquid fertilizer boost now and then.
💡 Tip: If your Anacharis starts to drop lower leaves, it may need more light or nutrients. Trim and replant healthy tops to keep it lush!
