Top House Plants For Aquaponics Fish Tank Recommendations
- BETTA TANK & HYDROPONIC PLANTER: See nature in motion through our Aqua-Ponic Tanks! Each fish tank is made from ultra-clear plastic, and replicates nature’s metabolic cycle by providing a healthy and symbiotic environment for fish and plants.
- SUGGESTED FISH: While Bettas are the most popular fish for our 1.4 Gallon Aqua-Ponic Tank, they can also house Bloodfin Tetras, White Cloud Minnows, Danios, and Guppies (1 – 3 fish). For Bettas, please decrease the water level an inch, giving them enough space to breath from the water’s surface.
- SUGGESTED PLANTS: Most indoor house plants and kitchen herbs are suitable for planting atop. This includes Peace Lily, Chinese Evergreen, Lucky Bamboo, English Ivy, Mint, Watercress, Chives, or any leafy Lettuce. We recommend using established plants instead of starting from seed.
- ADDITIONAL FEATURES: Our Aqua-Ponic Tanks come with ceramic planting media, which retains water and supports root growth for any plant you chose. To add water into the tank, simply water the plant, as if it’s in a pot of soil. As for feeding your fish, there’s several side openings that are more than large enough for a pinch of food.

Choosing the Best House Plants for Your Aquaponics Fish Tank
Aquaponics is a cool way to grow plants using fish waste as fertilizer. Picking the right house plants for your fish tank setup makes a big difference. This guide helps you choose the best ones.
Key Features to Look For
When you shop for plants, look for a few important things.
- **Nutrient Uptake Speed:** Fast-growing plants use up the fish waste quickly. This keeps the water clean for your fish. Think about plants that grow quickly, like lettuce or herbs.
- **Root Structure:** Plants with strong, fibrous roots work best. These roots handle being submerged or partially submerged well. They also grab nutrients efficiently.
- **Light Needs:** Consider the light you have available. Some plants need lots of bright light. Others grow fine in lower light. Match the plant to your setup’s lighting.
- **Toxicity to Fish:** This is super important! Make sure the plant will not harm your fish if they nibble on a leaf or if roots break off. Many common houseplants are toxic.
Important Materials and Setup
The materials supporting your plants matter a lot. You usually won’t plant directly into the fish tank water.
Most aquaponics systems use grow media instead of soil. Good media allows water and air to move around the roots easily.
- **Grow Media:** Look for materials like **clay pebbles (hydroton)** or **lava rock**. These materials are pH neutral and offer great surface area for beneficial bacteria to grow. Bacteria help convert fish waste into plant food. Avoid standard potting soil; it breaks down and fouls the water.
- **Plant Supports:** If you use rafts (floating systems), ensure the material holding the plant plug is safe and durable. Plastic net pots are common and effective.
Factors That Improve or Reduce Quality
What makes a plant thrive or struggle in your system?
Improving Quality:
Good water flow is key. Water must reach all the roots consistently. Healthy plants mean cleaner water for your fish. Also, ensure you have the right **nutrient balance**. Too much fish waste can burn some plants, while too little starves others. Regular testing helps you adjust feeding or stocking levels.
Reducing Quality:
Poor quality often comes from using the wrong plants. **Heavy feeders** (plants needing lots of nutrients) might strip the water too fast, leaving fish hungry. **Slow growers** do not clean the water effectively. Also, if you use chemically treated plants from a regular store, the pesticides can kill your fish. Always rinse new plants thoroughly or buy specialized aquaponics stock.
User Experience and Use Cases
How do people actually use these plants? The experience changes based on your goal.
If your goal is **food production**, you will choose leafy greens like kale, basil, or mint. These are great for beginners because they grow fast and you get to eat them!
If your goal is **aesthetics and water polishing** (cleaning the water), you might choose ornamental plants that look nice but aren’t necessarily for eating. Examples include certain types of Pothos (ensure it’s the non-toxic variety for your specific fish or keep roots fully submerged and leaves out of reach) or Spider Plants. These plants are hardy.
A great user experience involves easy maintenance. Plants that rarely need pruning or re-potting make the system enjoyable. Start simple. Success with easy herbs builds confidence for trying more complex vegetables later.
10 Frequently Asked Questions (FAQ) About House Plants for Aquaponics
Q: What are the best beginner plants for an aquaponics fish tank?
A: Leafy greens like lettuce and herbs such as basil and mint are excellent starters. They grow quickly and tolerate minor changes in water quality.
Q: Can I use regular soil-grown house plants directly in my system?
A: No, you should not. Regular soil contains pathogens and breaks down, polluting your fish tank water. Always remove soil and rinse roots completely before placing them in aquaponics media.
Q: Are Pothos safe for aquaponics?
A: Pothos roots are often used in aquaponics, but the plant leaves contain oxalates that can be mildly toxic if fish eat them heavily. It is safer to use them where fish cannot reach the foliage, focusing only on the roots cleaning the water.
Q: How much light do my aquaponics plants need?
A: This depends entirely on the plant. Vegetables need 6-8 hours of bright, direct light (often provided by grow lights). Herbs and decorative plants might only need moderate light.
Q: Do I need to fertilize my plants if I have fish?
A: Generally, no. The fish waste provides most necessary nutrients. However, if you grow heavy fruiting crops like tomatoes, you might need to supplement iron or calcium.
Q: What happens if my plant roots grow too long?
A: Very long roots can sometimes clog water pipes or block flow in the grow bed. Trim roots occasionally if they become excessively long, especially in deep water culture systems.
Q: How do I know if the fish waste is feeding my plants correctly?
A: Observe the plants. Yellowing leaves often mean a nitrogen deficiency. Stunted growth suggests a lack of nutrients overall. Test your water for ammonia, nitrite, and nitrate levels regularly.
Q: Which common houseplants should I absolutely avoid?
A: Avoid highly toxic plants like Dieffenbachia (Dumb Cane), Lilies, and many common succulents. Always research a plant’s toxicity before introducing it near fish.
Q: Should I use seeds or small starter plants?
A: Both work. Seeds are cheaper but take longer. Starter plants give you faster results and quicker water cleaning, which is great for new systems.
Q: Can I put the plant roots directly into the fish tank water?
A: Yes, this is called Deep Water Culture (DWC) or Kratky style. The roots must be submerged, and the leaves must stay above the water line to prevent rot and access air.
