Choosing the right aquarium plants is one of the most important decisions when creating a planted aquarium or aquascape. Aquatic plants can transform an ordinary aquarium into a beautiful underwater landscape, while also providing shelter and natural enrichment for fish and invertebrates.
However, not every plant is suitable for every aquarium. Different species have different requirements for lighting, nutrients, CO2, substrate, water chemistry and maintenance.
At Aquassi Ltd, we help customers choose aquatic plants that complement their aquarium design while also matching the equipment, livestock and level of maintenance they are prepared to provide.
Why Choose Aquarium Plants?
Aquatic plants provide much more than decoration.
A well-planted aquarium can create a natural environment with hiding places, swimming boundaries and grazing surfaces for aquatic life.
Plants also absorb nutrients and contribute to the overall biological ecosystem of the aquarium.
From simple beginner plants to demanding aquascaping species, there is an enormous range of aquatic plants available.
The key is choosing species that are appropriate for your particular setup.
Start With Your Aquarium Conditions
Before buying plants, consider the conditions inside your aquarium.
Important factors include:
- Aquarium size
- Lighting intensity
- Lighting duration
- CO2 availability
- Substrate
- Water temperature
- Water hardness
- pH
- Fertilisation
- Maintenance requirements
A plant that thrives in a high-tech aquascape may struggle in a low-light aquarium.
Choosing plants based on the conditions you can realistically provide is one of the best ways to achieve long-term success.
Low-Tech Aquarium Plants
Low-tech aquariums are designed without injected CO2 and often use moderate lighting.
There are many attractive plants that can grow successfully in these conditions.
Depending on the aquarium, suitable choices may include Anubias, Java fern, Cryptocoryne and various mosses.
These plants can be particularly useful for beginners because they generally require less intensive equipment than demanding carpeting and stem plants.
High-Tech Aquarium Plants
High-tech planted aquariums typically use stronger lighting, CO2 injection and carefully managed fertilisation.
These conditions allow aquarists to grow a wider range of demanding species.
High-tech aquascapes can produce dense carpets, vivid colours and rapid plant growth, but they also require greater attention to balance and maintenance.
Aquassi Ltd can help design a high-tech planted aquarium around your preferred plants and aquascaping style.
Foreground Plants
Foreground plants are generally shorter species used towards the front of an aquarium.
They can create carpets or low-growing areas that help frame the hardscape.
Popular carpeting choices can include species such as Monte Carlo, dwarf hairgrass and other suitable low-growing plants.
Foreground plants often benefit from good lighting and, depending on the species, CO2 injection.
Midground Plants
Midground plants provide the transition between foreground and background.
They can be positioned around rocks, driftwood and other hardscape features.
Suitable plants may include smaller Cryptocoryne varieties, compact ferns, Anubias and other appropriately sized species.
The objective is to create layers without allowing midground plants to completely hide the hardscape.
Background Plants
Background plants provide height and help create depth.
Stem plants and taller species can be used towards the rear of the aquarium.
They can provide colour, movement and a natural backdrop for smaller foreground and midground plants.
Fast-growing background plants may require regular trimming to prevent them from dominating the aquarium.
Stem Plants
Stem plants are popular in many planted aquarium styles, particularly Dutch aquascaping.
They can provide vibrant colours, contrasting leaf shapes and strong vertical growth.
Many stem plants grow quickly under good conditions, meaning regular pruning is important.
When trimmed correctly, stem plants can produce dense, attractive groups that form the structure of a planted aquascape.
Mosses
Aquarium mosses are extremely versatile.
They can be attached to rocks, driftwood and other hardscape materials to create an aged, natural appearance.
Moss can also provide shelter and grazing surfaces for shrimp and small aquatic animals.
Regular trimming is often necessary to prevent moss from becoming untidy or overwhelming the hardscape.
Rhizome Plants
Plants such as Anubias and Java fern have rhizomes that should generally not be buried beneath the substrate.
Instead, they can be attached to rocks or driftwood.
This makes them particularly useful for aquascapes where the substrate is not suitable for traditional root planting.
Root-Feeding Plants
Some aquatic plants obtain significant nutrition through their root systems.
Plants such as many Cryptocoryne species can benefit from nutrient-rich substrates or suitable root fertilisation.
When planting these species, ensure their roots have sufficient space to establish.
Floating Plants
Floating plants sit on or near the surface of the water.
They can provide shade and shelter for fish while absorbing nutrients directly from the water column.
However, floating plants can also reduce the amount of light reaching plants below them.
They should therefore be managed carefully in heavily planted aquariums.
Consider Your Aquascaping Style
The style of aquarium you want to create should influence your plant selection.
Iwagumi Aquascaping
Iwagumi layouts generally use relatively simple planting, often focusing on low-growing carpeting species that allow the stone arrangement to remain the main feature.
Nature Aquascaping
Nature aquascapes can combine foreground carpets, mosses, ferns, stem plants and other species to create a natural landscape.
Dutch Aquascaping
Dutch aquascaping relies heavily on contrasting groups of aquatic plants, colours, textures and heights.
Jungle Aquascaping
Jungle-style aquariums can use dense planting, tall background plants, mosses and epiphytes to create a lush underwater environment.
Biotope Aquascaping
Plant selection should reflect the geographical region or habitat being recreated.
Choosing Plants for Fish
The plants should also be suitable for the fish you intend to keep.
Some fish may uproot plants or damage delicate leaves, while others benefit greatly from dense vegetation.
Aquassi Ltd can help match plant selection with your livestock so that the finished aquarium works as both an aquascape and a suitable living environment.
Choosing Plants for Shrimp
Shrimp aquariums can benefit from dense planting and moss.
Plants provide additional surfaces for grazing and can create shelter for young shrimp.
Mosses, small-leaved plants and carefully arranged hardscape can create a complex environment where shrimp can explore and feed.
Lighting Requirements
Always check the lighting requirements of a plant before purchasing it.
Low-light plants can struggle under unsuitable conditions, while demanding plants may fail to thrive if there is insufficient light.
Lighting should be balanced with CO2 and nutrient availability.
Increasing lighting without addressing other requirements can contribute to algae problems.
CO2 Requirements
Some aquatic plants can grow successfully without injected CO2, while others perform significantly better when additional carbon is available.
If you want a densely planted high-tech aquascape, CO2 may be an important part of the system.
Aquassi Ltd can advise on CO2 requirements and help select plants appropriate for either low-tech or high-tech setups.
Growth Rate and Maintenance
Consider how quickly a plant grows before adding it to your aquarium.
Fast-growing plants can help establish a new aquascape quickly and compete with algae, but they may require frequent trimming.
Slow-growing plants generally require less pruning but can take longer to create the desired effect.
Your available maintenance time should therefore influence your plant selection.
Plant Size Matters
Always consider the mature size of a plant rather than how it looks when purchased.
A plant that looks perfectly proportioned in a small pot can eventually become too large for a nano aquarium.
Research the expected growth habit and plan the planting accordingly.
Buying Healthy Aquarium Plants
When purchasing plants, look for healthy specimens with strong colour, intact leaves and no obvious signs of disease or excessive algae.
Avoid introducing unwanted pests or contaminants into your aquarium.
Plants should be prepared appropriately before being introduced, particularly when moving between different aquarium systems.
Planting Your Aquarium
Different plants require different planting techniques.
Rooted plants should be planted deeply enough to establish themselves without burying sensitive structures.
Rhizome plants should generally be attached to hardscape rather than buried.
Stem plants can be planted as individual stems or small groups depending on the desired composition.
Take your time during planting. Good initial positioning makes future maintenance much easier.
Aquatic Plant Maintenance
Even the easiest aquatic plants require some maintenance.
Regular care may include:
- Removing dead leaves
- Trimming fast-growing plants
- Replanting cuttings
- Removing algae
- Checking roots
- Managing floating plants
- Cleaning around plant bases
Regular pruning also helps maintain the intended shape of an aquascape.
Avoid Plant Overcrowding
It can be tempting to buy lots of different plants when setting up your first aquarium.
However, too many species can make an aquascape look chaotic.
Using a smaller selection of complementary plants can often produce a much stronger design.
Aquassi Ltd can help create a plant palette that provides contrast while maintaining a cohesive appearance.
