Written ByHoward Parker

Ever look at your aquarium and feel like you’re in a constant battle with nitrates? You do your water changes, you manage your feeding, but those pesky numbers just seem to creep back up. It’s a common frustration for so many of us in the hobby.

What if I told you there’s a stunningly beautiful, natural, and almost effortless way to create a healthier ecosystem for your fish? A way to purify your water, slash your tank maintenance, and grow lush, vibrant houseplants all at the same time, right from your aquarium.

I promise, it’s not too good to be true. In this guide, we’re diving deep into the ultimate hydroponics plants list for your aquarium. We’ll explore the easiest plants to get started with, the amazing benefits for your tank, and a simple, step-by-step process to transform your aquarium into a thriving, self-sustaining work of art. Let’s get growing!

What is Aquarium Hydroponics (Aquaponics) and Why Should You Try It?

Before we jump into the plants, let’s clear up a common term. While many people search for “aquarium hydroponics,” the process we’re describing is more accurately called aquaponics. Don’t worry, it’s a simple concept!

Think of it as a perfect partnership. Your fish produce waste, which breaks down into ammonia and then nitrates. While high levels of nitrates are harmful to your fish, they are an excellent source of food for plants. By placing plant roots in your aquarium water, you create a natural filter. The plants absorb the nitrates, effectively cleaning the water for your fish. It’s a win-win!

The benefits of hydroponics plants list are truly incredible, especially for busy aquarists. You’re not just adding decoration; you’re building a tiny, balanced ecosystem.

  • Natural Nitrate Removal: This is the big one. These plants are nitrate-sucking powerhouses, leading to cleaner water and healthier fish.
  • Reduced Water Changes: With plants helping to keep your parameters stable, you’ll likely find you don’t need to do water changes as frequently. More time to enjoy your tank!
  • A Stable Ecosystem: Plants help create a more stable environment, reducing the wild swings in water parameters that can stress your fish.
  • Free Fertilizer: You’ll never have to buy fertilizer for these houseplants again! Your fish provide all the nutrients they need.
  • Stunning Aesthetics: The look of lush green foliage cascading down the side of an aquarium is simply breathtaking. It bridges the gap between your tank and your home decor.

The Ultimate Hydroponics Plants List for Your Aquarium

Alright, this is the fun part! Here is a curated list of plants that are known to thrive with their roots in an aquarium. I’ve broken them down by difficulty, so you can find the perfect match for your experience level. This is the core of our hydroponics plants list guide.

The “Can’t-Kill-‘Em” List for Beginners

If you’re new to this, start here. These plants are incredibly forgiving, resilient, and grow so fast you’ll see results in no time. Don’t worry—these are perfect for beginners!

  1. Pothos (Epipremnum aureum): This is the undisputed king of aquarium hydroponics. It’s incredibly hardy, grows like a weed, and its trailing vines look gorgeous. Just take a cutting, stick the stem in the water, and watch it go.
  2. Peace Lily (Spathiphyllum wallisii): Not only does it have beautiful, dark green leaves, but it can also produce its iconic white flowers in the right conditions. It’s a fantastic nitrate absorber. Important: Only the roots should be in the water; the main bulb (the crown) will rot if submerged.
  3. Lucky Bamboo (Dracaena sanderiana): Despite the name, it’s not actually bamboo. This plant is born to live in water. You can buy stalks at almost any garden center. Just make sure the leaves stay above the water level.
  4. Spider Plant (Chlorophytum comosum): Known for the little “spiderettes” it sends out, this plant is another super-easy option. The baby plantlets are perfect for tucking into the back of your filter or a suction cup planter.

Intermediate Plants for the Adventurous Aquarist

Once you’ve had some success with the basics, you might want to try something a little different. These plants are still quite easy but might require a bit more attention to lighting or placement.

  • Monstera Deliciosa (Swiss Cheese Plant): Yes, you can grow this trendy houseplant from your tank! It’s best for larger aquariums, as its root system can get quite extensive. The payoff is huge, with massive, iconic leaves growing above your setup.
  • Philodendron (various species): Very similar to Pothos, the Heartleaf Philodendron is another vining plant that does exceptionally well. Its heart-shaped leaves are a classic for a reason.
  • Syngonium (Arrowhead Plant): This plant grows vigorously and comes in a variety of colors, from green to pink to white. It’s a fast grower that will quickly help you create that lush, jungle look.

Edible & Herbaceous Options

Want to take your eco-friendly hydroponics plants list to the next level? Try growing some edible greens! These require more light and a well-stocked tank with plenty of nutrients, but it’s incredibly rewarding.

  • Lettuce and Leafy Greens: Varieties like romaine and leaf lettuce can be grown from starter plugs. You’ll need a strong light source directly above them.
  • Herbs: Mint, basil, parsley, and oregano are all great candidates. Imagine snipping fresh mint for your tea right from your aquarium!

How to Get Started: A Simple Hydroponics Plants List Guide

Feeling inspired? Getting started is easier than you think. This section covers how to hydroponics plants list and get them growing successfully in your tank.

Step 1: Choose Your Plant

Pick a plant from the list above that excites you. For your first attempt, I highly recommend a Pothos cutting. You can often get them for free from a friend or buy a small plant very cheaply.

Step 2: Prepare the Plant

This is the most important step. If you bought a plant in soil, you must remove all of it from the roots. Gently rinse the roots under lukewarm tap water until they are completely clean. Any soil left in your aquarium will decay, causing cloudy water and ammonia spikes.

Step 3: Place the Plant in Your Aquarium

You have a few options here. The key is to ensure only the roots are in the water, while the stem and leaves remain dry.

  • Hang-on-Back (HOB) Filter: The media compartment of a HOB filter is the perfect spot. Just tuck the roots into the filter media (like sponges or ceramic rings).
  • DIY Planters: You can cut holes in a piece of styrofoam or use a plastic soap dish with suction cups. Get creative!
  • Rimless Tanks: There are many commercially available plastic or glass planters that hang on the side of your tank, which are perfect for this.

Hydroponics Plants List Best Practices for a Thriving Setup

To ensure your new green friends flourish, follow these hydroponics plants list best practices. This simple care guide will make all the difference.

Lighting is Key

Your standard aquarium light is designed to penetrate water and is usually not enough for the emersed plants growing out of the top. The plants need their own light source. A sunny window is great, but a simple, inexpensive clip-on LED grow light aimed at the leaves will guarantee lush growth.

Nutrients and Fish Load

A moderately stocked community tank usually produces plenty of nitrates to feed a few plants. If you have a very lightly stocked tank or a huge number of emersed plants, you might notice signs of nutrient deficiency (like yellowing leaves). If so, you can supplement with an aquarium-safe liquid fertilizer.

Pruning and Maintenance

This is the easy part of your hydroponics plants list care guide. Simply snip off any yellow or dying leaves to keep the plant looking tidy. The roots will grow long and create a beautiful web in your tank, which provides great cover for shy fish and fry. If they get too long, you can trim them back without harming the plant.

Avoiding Common Problems with Your Hydroponics Plants List

Even with easy plants, you might hit a snag. Don’t worry! Here are some solutions to the most common problems with hydroponics plants list setups.

Problem: The leaves are turning yellow.
Solution: This is usually a sign of a nutrient deficiency. If your tank is lightly stocked, consider a comprehensive aquarium fertilizer. It could also be a lack of light, so ensure the leaves are getting several hours of bright, indirect light per day.

Problem: The base of the plant is mushy or rotting.
Solution: The crown of the plant (where the stem meets the roots) is likely submerged. This is a fatal mistake for most houseplants. Adjust the plant so that only the roots are touching the water.

Problem: The plant isn’t growing.
Solution: Patience! It can take a few weeks for a plant to acclimate to its new environment and start putting out new growth. Double-check your lighting and ensure your tank has some level of nitrates for it to feed on.

Creating a Sustainable and Eco-Friendly Aquarium

By incorporating plants this way, you’re doing more than just decorating. You’re creating a more sustainable hydroponics plants list ecosystem. This method reduces your reliance on frequent water changes, which conserves water. It closes the loop, turning fish waste into something beautiful and productive.

This is the heart of an eco-friendly hydroponics plants list. It’s a small-scale model of the natural cycles you see in rivers and lakes. You’re working with nature, not against it, to create a healthier home for your fish and a more beautiful space for yourself.

Frequently Asked Questions About Your Hydroponics Plants List

Will these plants harm my fish?

No, not if you choose from the list above. The plants themselves are not toxic when only their roots are in the water. In fact, the fish love the cover the long roots provide! Just be sure to thoroughly wash any pesticides off new plants before adding them.

Do I need to add extra fertilizer?

For most aquarists, the answer is no. A standard, well-fed aquarium provides all the nitrates and other trace elements these hardy plants need. You’ll only need to consider fertilizer if you have a very large number of plants or a very low fish stock.

Can I use any houseplant?

Definitely not! Many houseplants will rot immediately in water or are toxic. Stick to the tried-and-true list of water-loving plants in this guide to ensure success and safety for your fish.

How long does it take for the plants to start growing?

It typically takes 2-4 weeks for a plant to establish its new aquatic root system. After that initial period, plants like Pothos can grow surprisingly fast, sometimes putting out a new leaf every week!

Your Aquarium Is Ready for an Upgrade!

You now have everything you need to turn your aquarium into a beautiful, self-sustaining aquaponic setup. You’ve got the ultimate hydroponics plants list, you know how to prepare and place them, and you’re ready to troubleshoot any issues that arise.

This is one of the most rewarding projects in the aquarium hobby. It’s simple, inexpensive, and has a massive impact on the health and beauty of your tank. It’s a living, breathing piece of art.
