Planted tank basics and the best beginner plants
Live plants are the single biggest upgrade you can make to a freshwater tank, and the most over-complicated. You do not need pressurised CO2, high-output lighting, or a chemistry degree. A handful of hardy species, a sensible light, and a little fertiliser give you a healthier, better-looking, more algae-resistant tank.

Why live plants are worth it
Plastic and silk plants only decorate. Live plants do real work in the tank:
- They starve algae. Fast-growing plants compete with algae for the same light and nutrients, which is why a well-planted tank rarely has a serious algae problem.
- They improve water quality. Plants take up ammonia and nitrate directly, easing the load between water changes.
- They give fish security. Cover and broken sight lines reduce stress, encourage natural behaviour, and bring out better colour.
- They look alive, because they are. A planted tank ages into something better, not something faded and dusty.
Going low-tech (and what you can skip)
Planted tanks split roughly into two camps. High-tech tanks run strong lighting, pressurised CO2, and heavy fertiliser dosing to grow demanding carpets and fast, colourful stems. They look spectacular and are a lot more work, with a much smaller margin for error and a far higher algae risk if the balance slips.
Low-tech is the right starting point: hardy plants, a modest light, no injected CO2, and a little fertiliser. Growth is slower, but the tank is stable and forgiving, and the plants below all thrive this way. You can always add complexity later.
What you actually need: a few hardy species, a basic aquarium light on a timer, root tabs or a liquid fertiliser (more on which below), and patience.
What you can skip as a beginner: pressurised CO2, high-output lighting, and expensive specialist gear. None of it is needed for the plants in this guide, and all of it raises the algae risk if your nutrients and light are not balanced.
Planted does not mean self-cleaning. Live plants help with water quality, but they do not replace cycling or water changes. Still cycle the tank before adding fish, and keep up your usual water changes.
The best beginner plants
These are the species that survive beginner mistakes. Open any you are considering. The chip shows where each one goes in the tank.
Anubias
The hardiest plant in the hobby (Anubias barteri and its small "nana" forms). Thick, dark, leathery leaves that fish and snails leave alone, and it grows in almost any light.
Grows from a creeping rhizome, so do not bury it: glue or tie it to wood or rock and let the roots find their own hold. Slow-growing, which means its older leaves can collect spot algae in bright tanks. Almost impossible to kill.
Java fern
Another rhizome plant (Microsorum pteropus) that attaches to hardscape rather than rooting in substrate. Tall, textured green leaves and a tolerance for a wide range of conditions.
Like anubias, never bury the rhizome. It reproduces by growing tiny plantlets on its older leaves, which you can detach and attach elsewhere once they have a few roots. Undemanding and long-lived.
Cryptocoryne (crypts)
A large group of rooted plants (Cryptocoryne wendtii is the classic) in greens, browns, and reds. Excellent low-to-moderate-light mid-ground plants that fill in over time.
Plant the roots in the substrate and keep the crown above it. Crypts are famous for "melting" after planting or any big change, dropping most of their leaves; leave the roots in place and they grow back stronger. Root tabs suit them well.
Amazon sword
A large rooted plant (Echinodorus species) with broad, bright leaves that makes a striking background or centrepiece in a medium or larger tank.
A heavy root feeder, so it does best with root tabs or an enriched substrate. Give it room; a happy sword gets big. Otherwise hardy and forgiving in moderate light.
Vallisneria
Fast-growing grass-like ribbons (Vallisneria) that form a green curtain along the back of the tank. A hardy genus that even includes species native to Australia.
Plant the roots but keep the crown clear of the substrate. It spreads quickly by runners, so give it space and thin it when it takes over. One caution: liquid carbon (see fertiliser, below) can melt vallisneria, so go easy if you dose it.
Java moss
A versatile, undemanding moss (Taxiphyllum barbieri) that attaches to wood, rock, or mesh and grows in almost any light. Superb cover and foraging ground for shrimp and fry.
Just tie or wedge a little onto hardscape and let it spread; trim it to shape. It needs no substrate and no special care. Excellent in shrimp tanks and on driftwood.
Floating plants
Plants that drift on the surface with roots hanging below. Because they sit in the air, they grow fast, export nutrients quickly, and shade the tank, which makes them powerful algae fighters and a favourite of breeders.
The trade-off is that they block light to plants below and need thinning often. Important in Australia: some popular floaters such as water lettuce and Amazon frogbit are restricted in certain states (see buying plants in Australia), so buy from a local shop that stocks what is legal in your area.
Also worth a look once you have the basics down: water wisteria, hornwort, and bucephalandra (another rhizome plant, treated like anubias). Stick to this group and you will not go far wrong.
Light: enough, not too much
Every plant in this guide is a low-to-moderate-light plant, which means the basic LED that came with your tank is usually enough. You do not need an expensive light to keep them. If you are buying one, a simple plant-spectrum LED is plenty for low-tech; our aquarium lighting guide covers how to choose one and read the numbers.
The bigger mistake is too much light, not too little. Run your light on a timer for 6 to 8 hours a day and keep it consistent. Longer or brighter is not better: it pushes algae long before it helps these plants, and a strong light without matching CO2 and nutrients is the most common cause of algae in planted tanks. If algae appears, shorten the photoperiod before anything else. Our algae guide covers the light-and-nutrient balance in detail.
Feeding your plants
Plants draw nutrients from two places: the water column and the substrate. Where a plant feeds decides how you fertilise it.
Root feeders (vallisneria, amazon sword, and crypts) pull most of their food from the substrate. Feed them with root tabs such as Seachem Flourish Tabs, pushed into the substrate near the roots every few months.
Column feeders (anubias, java fern, mosses, and floating plants) take nutrients straight from the water. Feed them with a liquid all-in-one fertiliser such as Seachem Flourish, dosed weekly to the label.
In a stocked, low-tech tank, fish waste already supplies a lot of what plants need, so start with a light dose and only increase it if you see signs of deficiency (see care, below). Overdosing fertiliser, especially in low light, feeds algae rather than plants, so more is not better here either.
Liquid carbon (Seachem Flourish Excel) is an optional extra carbon source that can speed growth and double as an algae spot-treatment, but it can melt vallisneria, some mosses, and a few stem plants, and it harms shrimp if overdosed. It is genuinely useful, but not required for any plant here.
Substrate matters most for the root feeders. A tank built around them benefits from an enriched planted substrate, while attached and column plants do fine over plain gravel or sand with root tabs where needed. Our substrate guide compares the options.
Planting and ongoing care
Rooted plants (vallisneria, swords, crypts) go into the substrate roots-first, but keep the crown, where the leaves meet the roots, just above the surface. Burying the crown causes rot. Vallisneria and other runners spread sideways on their own, so plant them with room to fill in.
Trimming and propagation are where a planted tank pays off. Trim stem plants and replant the tops; split anubias, java fern, and bucephalandra at the rhizome; pull and replant vallisneria runners; and simply cut moss to shape. A few starter plants become a full tank within a season, at no extra cost.
If a plant struggles, the cause is usually light or nutrients. Holes and yellowing leaves point to a nutrient shortfall (dose a little more, or add root tabs for root feeders). Plants that sit still and grow algae on their oldest leaves usually have too much light for the nutrients available; shorten the photoperiod and check the algae guide. To gauge whether your tank counts as lightly, moderately, or heavily planted, our planting density calculator can estimate it from a photo.
Buying plants in Australia
Buy locally. Australia has strict biosecurity, and many aquarium plants sold freely overseas cannot be legally imported. Buying from Australian aquarium retailers is by far the simplest path, because reputable shops only stock plants that are legal to sell here. Importing plants yourself risks seizure, fines, and disappointment.
Watch for hitchhikers. New plants often carry pest snail eggs, and occasionally algae or pests, into the tank. Rinse and inspect new plants before adding them, and consider a plant dip if you want to be thorough. The cleanest option is tissue-culture plants, sold in sealed cups: they are grown sterile, so they arrive free of snails and algae, which makes them well worth the slightly higher price for a new tank.
Where to buy. Petbarn, Petstock, and dedicated aquarium shops carry the common hardy species and tissue-culture cups, and specialist Australian online plant sellers stock a wider range. For the plants in this guide, any decent local shop will have most of them.
Plants work best alongside the right foundation: choose a substrate that suits them, keep algae in check with the algae guide, and check your planting level with the planting density calculator. Browse fish that suit a planted community in the species directory.
