Top 10 Easy Aquarium Plants for Beginners (No CO₂ Needed)

Top 10 Easy Aquarium Plants for Beginners (No CO₂ Needed) | Aqualista

🌿 Start your planted tank journey with these bulletproof, no‑CO₂ plants — This guide lists the easiest aquarium plants that thrive under low light and require minimal care.

What Makes a Plant Easy for Beginners?

Easy plants tolerate low light (20‑40 PAR), survive without CO₂ injection, grow slowly, and resist common mistakes like irregular water changes or inconsistent fertilization.

The best beginner plants are forgiving. 2Hr Aquarist notes that plants like Anubias and Java fern can survive for weeks in a bucket of water. They do not need expensive lighting or CO₂. Many are rhizome plants that should be attached to hardscape, not buried. Others are root feeders that only need a root tab every few months. For a comprehensive list, see our beginner plants hub.

#1 – Anubias (Any Variety)

Anubias is the most forgiving aquarium plant. It has thick, dark green leaves and a creeping rhizome. Grow it in 10‑30 PAR, attach to wood or rock. Never bury the rhizome.

Anubias tolerates low light, low nutrients, and even neglect. 2Hr Aquarist calls it “unkillable.” Varieties include A. nana (small, perfect for nano tanks), A. barteri (large), and A. coffeefolia (ribbed leaves). Anubias grows very slowly (one leaf per month), so algae rarely grows on its leaves. Attach with super glue gel or cotton thread. Do not plant in substrate. If leaves get algae, reduce light intensity. For a detailed care sheet, see our Anubias care guide.

🌿 Anubias Light: 10‑30 PAR | CO₂: not needed | Growth: very slow
Placement: attach to wood/rock | Fertilizer: liquid (low dose)

#2 – Java Fern (Microsorum pteropus)

Java fern is a rhizome fern that grows in 10‑40 PAR, no CO₂. It reproduces via plantlets on leaf tips. Attach to hardscape – never bury the rhizome.

Java fern is almost as tough as Anubias. It comes in regular, narrow leaf, trident, and Windelov varieties. 2Hr Aquarist notes that it propagates easily – baby plants form on leaf edges. Java fern prefers soft, slightly acidic water but adapts to most conditions. It is sensitive to high light (above 60 PAR); leaves may turn transparent. It does not need CO₂, but a low dose of liquid fertilizer keeps leaves green. For propagation, see our Java fern propagation guide.

Placement: attach to wood/rock | Propagates via plantlets

#3 – Cryptocoryne wendtii

Cryptocoryne wendtii is a rosette plant that grows in 20‑50 PAR, no CO₂. It tolerates hard water and low light. It may “melt” (leaves dissolve) when first planted but will regrow.

Crypts are heavy root feeders. Insert a root tab under each plant every 3‑4 months. 2Hr Aquarist explains that melting is a normal stress response. Do not remove the plant; within 2‑3 weeks, new leaves will emerge. Cryptocoryne wendtii comes in green, bronze, red, and brown (“Mi Oya”, “Flamingo” – pink). It grows 4‑8 inches tall. It does not need CO₂, but moderate light (40‑50 PAR) brings out deeper colors. For more, see our Cryptocoryne guide.

Placement: substrate (root tabs) | May melt initially

#4 – Amazon Sword (Echinodorus bleheri)

Amazon sword is a large background plant that grows up to 20 inches. It needs moderate light (30‑60 PAR), root tabs, and no CO₂. Perfect for medium to large tanks.

Swords are heavy root feeders. Without root tabs, they develop yellow leaves (nitrogen deficiency). Aquarium Co‑Op recommends placing one root tab directly under the crown every 3 months. Swords propagate via runners that produce baby plants. They do best in sand or fine gravel (2‑3 inches deep). Light intensity should be at least 30 PAR; below that, leaves become smaller and pale. For more background plant options, see our beginner plants hub.

#5 – Java Moss

Java moss attaches to any surface and grows in 10‑50 PAR, no CO₂, no fertilizer. It forms a soft carpet or moss wall. Ideal for shrimp tanks and fry cover.

Java moss (Taxiphyllum barbieri) is a versatile moss. 2Hr Aquarist notes that it grows in virtually any light. It can trap debris, so gentle water flow and occasional shaking are helpful. To create a moss wall, sandwich moss between two plastic mesh sheets. Java moss does not need CO₂ or fertilizer. It propagates by breaking off and reattaching. Trim with scissors to keep it neat. For other easy mosses, see our low‑light plant guide.

Placement: attach to mesh, wood, or rocks

#6 – Marimo Moss Ball

Marimo moss balls (Aegagropila linnaei) are actually algae balls. They grow in 10‑30 PAR, no CO₂, no fertilizer. Just place on substrate and turn weekly to keep their round shape.

Marimo balls are one of the easiest “plants” (though they are not true plants). They grow extremely slowly (millimeters per year). 2Hr Aquarist recommends turning them weekly so all sides receive light. They do not require any special care. Marimo balls can be cut in half and rolled into new balls to propagate. They are safe with all fish and shrimp. For more easy foreground options, see our carpeting plants guide.

#7‑10 – Floating Plants, Hornwort, Water Wisteria & Bucephalandra

Floating plants (Salvinia, Frogbit) reduce algae. Hornwort grows fast and absorbs nutrients. Water wisteria is a stem plant that can grow emersed. Bucephalandra is a slow rhizome plant with metallic leaves.

Floating plants are excellent for nutrient export and shading. Hornwort (Ceratophyllum demersum) can be floated or planted; it grows rapidly and competes with algae. Water wisteria (Hygrophila difformis) is a fast‑growing stem plant that does well in low light. Bucephalandra is a slow‑growing rhizome plant that comes in many colors (blue, purple, red). All of these require no CO₂ and tolerate low to moderate light. For more details, see our floating plants guide and low‑light plants hub.
