What Exactly Is an Aquarium Plant Hanger (And Why You’ll Love It)
Think of an aquarium plant hanger as a small, specialized pot or basket that clips onto the rim or suctions to the side of your tank. Its purpose is to hold a plant’s roots in the water column while allowing the leaves and stems to grow up and out into the open air—a style known as emersed growth.
This simple device is a game-changer for aquarists of all levels. It’s not just about aesthetics; it’s about creating a more dynamic and healthy ecosystem. Let’s dive into the core benefits of an aquarium plant hanger.
- Natural Nitrate Removal: The number one reason I recommend these to fellow hobbyists is for their incredible power as natural filters. Terrestrial plants like Pothos are nitrate-devouring machines. Their roots will pull nitrates—the final byproduct of the nitrogen cycle—directly from your water, helping to keep levels low and reduce the frequency of water changes.
- A Stunning New Aesthetic: Hangers add verticality and a new layer of life to your setup. The contrast between the submerged aquascape and the cascading emersed leaves creates a breathtaking, natural look that mimics a riverbank or shoreline.
- Provides Shade and Security for Fish: The dangling roots create a complex, shaded network that many fish, especially shy species like Bettas, Gouramis, and various tetras, absolutely love. It gives them a safe place to hide, rest, and even spawn.
- Incredibly Easy to Set Up: Unlike some complex aquascaping projects, setting up a plant hanger takes just a few minutes. Don’t worry—it’s a perfect project for beginners!
Choosing Your Perfect Hanger: A Buyer’s Guide
Not all hangers are created equal. The right choice depends on your tank type, your aesthetic preferences, and your goals. Here’s a breakdown of what to look for in this essential aquarium plant hanger guide.
Types of Hangers
You’ll generally find three main styles on the market:
- Over-the-Rim Hangers: These are the most common and stable. They have a hook that simply rests over the edge of your aquarium glass. They come in various hook sizes, so measure your tank’s rim thickness before you buy!
- Suction Cup Hangers: These offer more flexibility in placement, as you can stick them anywhere on the glass. However, be sure to buy from a reputable brand with strong suction cups, as cheaper ones can fail over time.
- Floating Baskets: While less common, these are porous rings or baskets that float on the surface, allowing you to place plants in the middle of your tank. They are great for providing cover in larger aquariums.
Material Matters: The Rise of the Sustainable Aquarium Plant Hanger
The material of your hanger is crucial for the safety of your aquatic inhabitants. Always look for options that are 100% aquarium-safe.
Many modern hangers, especially from small businesses on platforms like Etsy, are 3D printed. Look for those made from PETG plastic. It’s a non-toxic, durable, and food-safe material that won’t leach harmful chemicals into your water. This makes it an excellent choice for an eco-friendly aquarium plant hanger.
Avoid hangers made from unknown or cheap plastics, as they can degrade over time and pose a risk to your fish and invertebrates. A sustainable aquarium plant hanger is one that is built to last and keep your tank safe for years to come.
The Best Plants for Your New Hanger: Our Top Picks
Here’s the fun part! You can’t just stick any houseplant in water and hope for the best. You need plants that are happy to have their “feet” wet permanently. The great news is that some of the most beautiful and easy-to-care-for houseplants are perfect for the job.
Here are my tried-and-true favorites:
- Pothos (Epipremnum aureum): The undisputed king of aquarium hanger plants. It’s incredibly hardy, grows fast, and is a nitrate-sucking champion. Golden, Marble Queen, and Neon varieties all look fantastic.
- Peace Lily (Spathiphyllum): Known for its beautiful white flowers and lush, dark green leaves. Just make sure only the roots are submerged, as the bulb (or crown) can rot if it stays wet.
- Monstera (Monstera adansonii or deliciosa): For a truly dramatic, jungle-like effect, nothing beats a Monstera. A single cutting can grow into a massive, impressive feature over time.
- Philodendron (Philodendron hederaceum): Similar to Pothos, the heart-leaf Philodendron is another vining plant that is nearly foolproof. Its velvety leaves are a beautiful addition.
- Spider Plant (Chlorophytum comosum): These are very forgiving and will send out “pups” or baby plants that can also be placed in hangers, allowing you to propagate them endlessly.
A crucial safety tip: Many of these plants (like Pothos and Peace Lilies) are toxic if eaten by cats or dogs. They are perfectly safe for your fish, but be mindful of placement if you have other pets in the house!
How to Set Up Your Aquarium Plant Hanger: A Step-by-Step Guide
Ready to get started? This is the core of our how to aquarium plant hanger tutorial. It’s a simple process that you can complete in under 15 minutes.
- Prepare Your Plant Cutting: Take a healthy cutting from a mother plant. Ensure the cutting has at least one or two nodes—the little brown bumps on the stem where roots and leaves grow from. This is where the new roots will sprout. If you’re using a plant that already has roots, gently rinse off all the soil under lukewarm tap water.
- Choose Your Hanger and Location: Pick the hanger that best fits your tank’s rim. I recommend placing it near the back corner of your tank. This keeps it from getting in the way during maintenance and often creates a more natural look.
- Add Your Substrate (Optional but Recommended): While not strictly necessary, adding a porous substrate like LECA (lightweight expanded clay aggregate), aquarium gravel, or lava rock into the hanger gives the roots something to grip onto. This provides stability and helps anchor the plant.
- Place the Plant in the Hanger: Gently thread the stem and any existing roots through the slots in the hanger. Make sure the nodes are below the waterline and the leaves are well above it. Carefully add your chosen substrate around the roots to hold the cutting in place.
- Position the Hanger on the Tank: Hook the hanger over the rim or attach it to the glass. Adjust the plant so it’s sitting upright and looks its best. That’s it! You’re done.
Long-Term Success: The Aquarium Plant Hanger Care Guide
Your work isn’t over once the hanger is on the tank. To ensure your new plant thrives, you’ll need to follow a few aquarium plant hanger best practices. Don’t worry, it’s incredibly low-maintenance!
Light and Nutrients
Your plant needs two things to thrive: light for its leaves and nutrients for its roots. The roots will get plenty of nutrients (nitrates, phosphates) from your aquarium water. In fact, you’ll find you don’t need to dose as many fertilizers in the water column anymore!
For light, the ambient room light is often enough for low-light plants like Pothos. If your room is dark, consider positioning your aquarium light so some of it spills over to illuminate the leaves.
Root Maintenance
Over time, the roots will grow into a massive, tangled web inside your tank. This is a good thing! However, if they get too long or start to look unruly, you can trim them. Just like pruning leaves, trimming the roots encourages bushier, healthier growth. I recommend trimming them back by about a third every few months. This is a key part of any good aquarium plant hanger care guide.
Troubleshooting: Common Problems with Aquarium Plant Hanger Setups
Even with a project this simple, you might run into a snag. Here’s a quick guide to solving the most common problems with an aquarium plant hanger.
Problem: My plant’s leaves are turning yellow.
Solution: This is usually one of two things. First, it’s normal for one or two of the lowest leaves to yellow and fall off when the plant is first acclimating. If it continues, it’s likely a nutrient deficiency. While your tank water provides nitrates, it might be low in potassium or micronutrients. A single pump of an all-in-one liquid fertilizer into the tank once a week can often solve this.
Problem: The roots are mushy or rotting.
Solution: This typically happens when part of the plant that isn’t supposed to be wet is submerged. For plants like Peace Lilies, ensure the crown (the base where all the stems meet) is completely above the water. For cuttings, make sure only the stem and nodes are submerged, not any leaves.
Problem: My hanger keeps falling off!
Solution: This is a suction cup issue. Remove the hanger, clean both the suction cup and the spot on the aquarium glass with rubbing alcohol to remove any biofilm, and reattach firmly. If it continues, the suction cup may have lost its effectiveness, and it’s time for a replacement.
Frequently Asked Questions About Aquarium Plant Hangers
Can I use any houseplant in my aquarium plant hanger?
No, definitely not! Many houseplants will quickly rot if their roots are permanently submerged. Stick to the proven winners like Pothos, Philodendron, Monstera, Peace Lily, Spider Plant, and Syngonium. Always research a plant before adding it to your tank.
Will the plant roots harm my fish?
Quite the opposite! The roots are completely safe and provide excellent cover and enrichment for your fish. Many species, from tiny shrimp to larger Bettas, love exploring and hiding in the root systems. The only exception would be if a root rots, which you should trim away immediately.
Do I need to fertilize the plants in the hanger?
Usually, no. The fish waste and leftover food in your aquarium provide a constant supply of nitrates and phosphates, which are the primary nutrients these plants need. If you notice yellowing leaves, a small dose of a comprehensive liquid aquarium fertilizer can help provide missing micronutrients.
How do I clean the hanger itself?
Over time, the hanger might grow a bit of algae or biofilm. Every few months, you can simply remove the plant, take the hanger to the sink, and scrub it with an old toothbrush or sponge. Avoid using soap; hot water is all you need. Then, place the plant back in and return it to the tank.
