Most aquarium hobbyists think that to achieve live planted aquariums, you need expensive lighting, pressurized CO₂, and high maintenance. While this can be true for an advanced aquascape, most people's home aquariums do not need high-tech equipment to be successful.

Actually, most common aquarium plants originated from shaded rivers, streams, or forest streams where light does not pass through readily. Low-light aquarium plants have been adapted to average light levels and can thrive with a good-quality aquarium LED lighting system with some routine care.

Whether you're beginning your first planted tank, want to get rid of your green tank, or wish to have a nice planted aquarium with little effort, low-light planted plants are always your best choice. With the planted tank lighting system and basic care, you can still have a green underwater world.

Why Low-Light Plants Are Perfect for Beginners

Many people wrongly assume that more light means better plants, but this isn't often the case, as too much can cause a lot more trouble than not enough. 

A lot of people will give up on plant growth as slow and prolong their light periods from 8 hours a day to 10 or 12, which simply will bring on algae very quickly before it affects the plant's growth. 

Plants suited for lower light have natural growth speed and are very forgiving in many ways, including water conditions, feeding, and lighting, requiring minimal trimming, and can grow in any conditions and often will live without CO₂. Best for community tanks or betta tanks and all low-maintenance freshwater aquariums.

These plants can also save you a lot of money; as in most planted tanks, most will do brilliantly under a decent aquarium LED light with the right moderate plant tank lighting and regular water changes, occasional dosing of root or liquid fertilizers.

10 Low-Light Aquarium Plants That Actually Thrive

Not all plants labeled "easy" will thrive with a novice. The following plants are reliably good performers under moderate lighting with no CO₂ or supplemental nutrients.

Anubias

Very hardy with dark green leaves that hold up to quite a bit of neglect. Grows slowly, but grows, and can be attached to hard scape such as wood or rocks. Do not cover the rhizome with substrate, or it will rot.

Java Fern

Another one that needs nothing. It feeds off of water nutrients, not roots. It looks good in any tank, adding some wave motion. Best placed as a mid-ground accent.

Cryptocoryne Wendtii

Crypt Wendi comes in greens, bronzes, or reddish varieties. It will "melt" its leaves when first placed in a tank due to the change in conditions; healthy roots will sprout new leaves in just a few weeks.

Java Moss

This hardy and very adaptable plant will grow all over your rocks, wood, and décor. It provides a refuge for shrimp and baby fish, while also cleaning your water up. Just trim it off as it gets too thick if you want it tidy.

Amazon Sword

If you have a medium to large tank with low light, this makes a great centerpiece plant. It has long leaves that grow from the base, and it will prefer some root tabs if you have very low nutrients in your substrate.

Water Wisteria

This plant outpaces most low-light plants with how fast it grows, and can help absorb some excess nutrients from your tank, thus keeping algae down. You can plant this, or just leave it to float on the surface.

Hornwort

Hornwort can be planted in the substrate, or you can leave it free-floating in your fish tank. Its rapid growth helps absorb some of the excess nutrients and provides some cover for fish.

Vallisneria

These plants produce extremely long leaves that just sway and flow in the current of the tank to produce a wonderful effect in the midground or background. They are great if you plan on planting a wall of them, as they spread from runners to create that effect easily.

Marimo Moss Balls

This is a special type of mossy algae. It doesn't do much, and is extremely low maintenance, but it adds visual interest and can be beneficial to the tank's quality.

Bucephalandra

These are similar to Anubias, but some varieties come in very nice colors. Like the Anubias, you can attach these to wood or rocks, and they do great under low light conditions, though they may grow more slowly than Anubias.

How Much Light Do Low-Light Aquarium Plants Need

A question many new keepers ask is whether their plants survive under standard LED lighting. The answer is yes! Most low-light plant species are content with a few 6-8 hours of medium-intensity aquarium LED lighting per day. Consistency is far more important than intensity.

A timer is strongly recommended. The consistency in the light period will help you avoid over-lighting your plants and killing them as you keep trying to get them to grow.

Common Mistakes That Slow Plant Growth

Even easy-going low-light plants can falter on common errors:

1. Growth will be slow and not immediate: This is expected with low-light species. You should monitor the development of new leaves instead of fast growth.
2. Not fertilizing enough: Root-feeders like Amazon Swords do better with root tabs, while water-column feeders appreciate being given some liquid fertilizer occasionally.
3. Planting the rhizome of certain plants: Anubias and Java Fern, is prone to rot if their rhizomes are planted in the substrate.
4. Over-cleaning or over-lighting: An aquarium is likely to develop a little bit of algae and some biofilm in a healthy planted system. Stability should be prioritized over cosmetic cleanliness.

Simple planted tank combinations for various tank sizes:

• 10-Gallon Tank: Anubias Nana, Java Fern, Java Moss
• 20-Gallon Tank: Amazon Sword, Cryptocoryne Wendtii, Anubias, Java Fern
• 40-Gallon Tank: Vallisneria for the background, Amazon Sword as a centerpiece

Cryptocoryne for the midground, Anubias on driftwood, Java moss for accents. All of these provide different textures and heights, which add depth to the planted aquarium, and they are all low-maintenance plants.

Frequently Asked Questions

Q1: Can low-light plants grow in an aquarium without CO₂?

A1: Most plants that thrive in a low-light tank do so without CO₂. They will just not grow as fast as they would in high-tech conditions.

Q2: Do aquarium plants need fertilizer at all?

A2: The occasional root tab or liquid fertilizer helps with long-term growth.

Q3: Can aquarium plants grow under LED light?

A3: Definitely! Moderate LEDs over the tank for 6-8 hours a day are ideal for low-light aquarium plants.

What Is Causing My Aquarium Plants to Turn Brown

Sometimes the tank may lack nutrients, the leaves may just be too old, or the plants have not yet adjusted to the tank. Keep an eye on any new growth the plant is showing, as this is an indicator of the plant's health.

Conclusion

You don't need special equipment to have a beautiful planted aquarium. Low-light planted plants, like Anubias, Java Fern, Cryptocoryne Wendtii, Java Moss, and Amazon sword, are very sturdy, and they do not need high light. The plants will look great and add natural beauty to the tank without so many tasks. Simply keeping the aquarium light turned on and off for 6-8 hours every day with regular water changes will do. For aquarium light solutions, Seaoura aquarium lights can offer controllable spectrum and brightness, plus built-in timers, which is perfect for your low-light planted aquarium!
