Find the Best Live Aquarium Plants & Substrates for Your Fish Tank
Best Live Aquarium Plants for Different Needs
Different fish species have unique needs when it comes to live aquarium plants, so tailoring your aquascape to the specific habits and requirements of your fish is essential. For example, bettas thrive in a tank with plenty of cover and visual interest. Live plants like Java Fern, Anubias, Vallisneria, and Anacharis not only add natural beauty but also offer bettas places to hide and establish territories. These species are hardy enough to withstand occasional nips and gentle water currents while providing continuous natural filtration and oxygenation through their photosynthetic activity.
For smaller setups, such as 5-gallon tanks, space-efficient options like Bucephalandra, Anubias Nana, and Java Ferns work beautifully without overcrowding the limited space.
Best plants for tropical fish
In tropical fish aquariums, incorporating a variety of plant families helps create a natural, balanced ecosystem while enhancing both aesthetics and water quality. Stem plants like Rotala, Ludwigia, and Anacharis provide fast-growing, oxygen-rich greenery, perfect for absorbing excess nutrients and reducing algae. Anubias and Bucephalandra, known for their hardy, slow-growing nature, thrive when attached to rocks or driftwood, making them excellent low-maintenance choices. Sword plants, such as Amazon Swords and Red Flame Swords, develop broad, vibrant leaves that serve as shelter for fish while anchoring the aquascape.
For added texture and coverage, Vallisneria and Cryptocoryne offer elegant, flowing leaves that create a lush, jungle-like effect. Floating plants like Red Root Floaters, Frogbit, and Salvinia help diffuse light, reduce algae growth, and provide shaded areas for fish that prefer low-light environments. Whether you're designing a densely planted jungle or an open, minimalist aquascape, choosing the right mix of plant species ensures a healthy, thriving aquatic environment for your fish.
Can I use live plants with Goldfish?
Goldfish, on the other hand, pose a special challenge due to their tendency to forage and nibble on live plants. While some aquarists experiment with Java Fern and Crinum Calamistratum, these species often do not withstand the goldfish’s active feeding habits. The most dependable choice for goldfish tanks is Anubias, whose tough, leathery leaves are less palatable and more resistant to damage. This makes Anubias the go-to option for maintaining a lush, live-plant environment in a goldfish aquarium, ensuring that the natural filtration and oxygenation benefits remain consistent.
Best Plants for Discus Fish
For Discus aquariums, the scenario shifts again due to the higher water temperatures these sensitive fish require—typically around 84°F or above. Not all plants can tolerate these warmer conditions, so only species that are rated for high temperatures should be used. Suitable options include certain sword plants, Anubias, Cryptocoryne species, and select high-temperature stem plants. These plants are robust enough to handle the heat while still offering the benefits of oxygenation, shelter, and natural nutrient absorption, all of which contribute to a stable and stress-free environment for Discus.
1. Lighting:
Start by ensuring you have the right lighting for your planted tank. Many kit lights and off-brand options can be difficult to work with and may not provide the optimal spectrum or intensity for healthy plant growth. At Nature Aquariums, we can help you choose the perfect light to match your existing setup. Whether you’re considering upgrading your light or starting a new tank from scratch, our in-house tested planted tank lights are designed to deliver the best results for your budget and aquascaping goals.
2. Substrate & Soil for Planted Aquariums:
Choosing the right substrate is essential for the health and growth of rooted aquarium plants. At Nature Aquariums, we recommend UNS Controsoil for areas where rooted plants will be placed, thanks to its superior nutrient retention and gradual release. This high-quality substrate provides a rich source of essential nutrients directly to plant roots, promoting vigorous growth while helping to maintain a stable nitrogen cycle.
What makes UNS Controsoil unique is its ability to be added to existing aquariums without causing a major ammonia spike, unlike many big-box store brands. This means you can upgrade your substrate without disrupting your tank’s delicate balance. For a customized aquascape, consider combining Controsoil with sand or gravel to create natural transitions and textural contrasts.

3. Water Flow:
Good water circulation is essential for maintaining water quality and distributing nutrients evenly throughout the aquarium. Ensure that your filter is appropriately sized for the fish you keep and provides steady water flow without creating strong currents that might disturb delicate plants. If your current setup needs an upgrade, we stock a large assortment of planted aquarium-rated filters at great low online prices to suit every tank’s requirements.
4. Fertilization:
Fertilization doesn’t have to be guesswork. Bring us a water sample, and we will digitally analyze your tank’s chemistry to guide you with a custom fertilization prescription. We offer some of the finest fertilizers from around the world, including Aquarium Coop Easy Green, UNS Min and Max, the 2Hr Aquarist APT line, and Seachem products, ensuring your plants receive the balanced nutrients they need for optimal growth.
5. Water Chemistry:
Maintaining optimal water chemistry is key to the health of your aquarium. With our advanced digital water testing services, we can create a comprehensive profile of your tank and track your water parameters over time. Our experts will help you achieve the ideal alkalinity and general hardness levels to keep your fish happy and your plants lush, ensuring a stable and thriving aquatic ecosystem.
6. CO₂ – Or Not:
One common question is whether to use CO₂ injection in your tank. Many plants can thrive without additional CO₂, especially if you’re working with lower light levels, which results in slower but steady growth. However, if you’re aiming for lush growth, vibrant red plants, or dense carpeting plants, a stronger light, daily fertilization, and a CO₂ system are necessary. We offer full instructions on both approaches and provide high-quality, affordable CO₂ systems as well as refill services for CO₂ tanks, so you can choose the best option for your aquascape.
7. Maintenance:
Regular maintenance is the cornerstone of a healthy planted aquarium. Simple tasks like routine water changes, scheduled fertilization, and occasional pruning will keep your tank looking its best. If you prefer low-maintenance setups, consider using hardy species such as Anubias, Java Ferns, Bucephalandras, Crypts, and Sword plants that require minimal pruning. For those who enjoy a more hands-on approach, fast-growing stem plants like Ludwigias, Rotalas, and various ground covers offer an engaging challenge, as they demand frequent trimming and nutrient adjustments.
Summary
By carefully selecting plants tailored to the specific needs of your fish—whether it’s providing hiding spots for a betta, creating a lush environment for a tropical community tank, offering durable, goldfish-resistant greenery, or choosing heat-tolerant species for Discus—you can cultivate a thriving, self-sustaining ecosystem. Thoughtful plant selection not only enhances the beauty of your aquarium but also improves water quality, aids in natural filtration, and provides essential nutrients to support the long-term health of your fish.
