Top 10 Easy Aquarium Plants Low Light Roundup: No CO2 Picks

Most beginner planted tanks fail not because the plants are wrong but because the lighting and CO2 demands were never matched to the aquascaper. The top 10 easy low light plants here grow under 30 PAR, accept Singapore tap water at GH 2-4, and need no pressurised CO2 injection. This roundup from Gensou Aquascaping at 5 Everton Park ranks species by tolerance for neglect first, growth rate second. Each entry covers placement zone, propagation method and SGD pricing from the local nursery circuit.

1. Java Fern (Microsorum pteropus)

The unkillable epiphyte. Tied or glued to wood and rock, java fern grows 20-30cm tall under any light from 15 PAR upward. Propagates through plantlets that drop off mature leaves. SGD 5-12 per portion at most local shops. Bury the rhizome and it rots — always mount above substrate.

2. Anubias Barteri and Nana

Slow-growing rhizome plant with thick leathery leaves. Place mid-tank, attached to wood. Anubias barteri reaches 25cm, nana caps at 12cm, petite stays under 5cm. SGD 8-25 depending on size and variety. Stock a live aquarium plant range for fresh imports.

3. Cryptocoryne Wendtii

Substrate-rooted rosette plant in green, brown and red morphs. 15-20cm tall, suits midground placement, runs through the substrate via runners. SGD 6-12 per portion. Expect “crypt melt” within a week of replanting — leaves dissolve and regrow from the rhizome within three weeks.

4. Java Moss (Taxiphyllum barbieri)

The default beginner moss. Attaches to anything porous, tolerates low light and any water chemistry, hosts shrimp fry brilliantly. SGD 5-10 per portion. Trim weekly to prevent the inner mat from suffocating. Pair with mesh or super glue for fast attachment to hardscape.

5. Hornwort (Ceratophyllum demersum)

Floating or planted stem plant with feathery whorls. Grows 5-10cm a week even in low-tech setups. SGD 3-8 per bunch. Drops needles when the lights are too strong — counterintuitive for a plant — so keep light intensity moderate.

6. Vallisneria (Vallisneria spiralis, V. nana)

Tape grass for background placement. Reaches 40-60cm tall. Spreads through runners aggressively once established. SGD 4-8 per portion. Trim leaves at the substrate, not midway up — cut tips brown back.

7. Amazon Sword (Echinodorus bleheri)

Centrepiece rosette plant, 30-50cm tall, needs root tabs to thrive long-term. SGD 8-20 per portion. Watch leaf colour: pale yellow indicates iron deficiency, easily corrected with a root tab from the live aquarium plant range.

8. Water Wisteria (Hygrophila difformis)

Fast-growing stem with deeply lobed leaves above water and finer lacy growth submerged. SGD 4-8 per bunch. Reaches 40cm in two months in low-tech setups. Pinch off the top to encourage bushier side shoots.

9. Dwarf Sagittaria (Sagittaria subulata)

Carpet-like grass in low to medium light. 8-15cm tall depending on light intensity. SGD 5-10 per portion. Spreads through runners. The lowest-light alternative to dwarf hairgrass — significantly more forgiving.

10. Pearl Weed (Hemianthus micranthemoides)

Bright green stem with tiny rounded leaves. Trims into a compact bush or grows as a foreground carpet. SGD 5-12 per portion. The exception in this list — pearl weed prefers medium light but tolerates low light with slower growth. Pair with a nutrient-rich substrate for stable growth.
