Here's a conversation that plays out in the Indian aquarium hobby every single day.
Someone wants a planted tank. They look it up, get excited, then see the words "aquasoil substrate," "capping layer," "root tabs," and "nutrient dosing schedule." They spend a weekend reading about ADA Amazonia and whether they need buffering sand. They watch three YouTube videos about substrate layering. And then they either spend ₹2,000–₹5,000 setting it up or they give up entirely and go back to gravel with plastic plants.
Neither is the right outcome. Because here's what those tutorials don't lead with: a huge number of the most beautiful aquarium plants don't need soil at all.
They grow attached to rock and driftwood. They float. They drift in the water column. They thrive on nothing but good water, decent light, and the occasional dose of liquid fertilizer. No substrate required. No mess. No re-scaping every time you want to add a fish.
As we explored in Are Your Aquarium Plants Dying?, many plant failures in Indian tanks come down to wrong care routines, and one of the most common mistakes is planting soil-free species into substrate, burying their rhizomes, and watching them rot. This post is the other side of that conversation: a complete guide to the plants that genuinely prefer life without soil.
Why Go Soil-Free?
Before we get into the list, it's worth being clear about what "soil-free" actually means for your tank.
Epiphytes are plants that attach to hardscape rocks, driftwood, lava stone, and absorb nutrients directly from the water column rather than from the substrate. Their roots are anchors, not feeding organs. Burying them is actively harmful.
Floating plants live at the surface, their roots dangling into the water, pulling nutrients directly from the water column. No attachment, no substrate interaction at all.
Stem plants and moss can technically grow in substrate but do perfectly well, often better tied to hardscape or left free-floating while they establish.
What all of these have in common: they respond to liquid fertilization, not root feeding. Which is exactly why products like Sunken Garden Fertilizers, formulated for water column delivery, are the ideal companion for a soil-free planted tank.
The Top 10
1. Java Fern (Microsorum pteropus)
Difficulty: Beginner | Light: Low to medium | CO₂: Not required
If there's one plant that belongs on every beginner's list, it's Java Fern. Native to Southeast Asia, it's nearly indestructible, tolerant of low light, wide temperature ranges, hard water, and even the kind of benign neglect that kills most plants.
Java Fern attaches to rock or driftwood via a dark, creeping rhizome. Tie it on with fishing line or fix it with aquarium-safe superglue, and within a few weeks, the roots will grip on their own. The broad, dark green leaves grow slowly and steadily, giving the tank a wild, natural look without any effort.
One critical rule: never bury the rhizome. If it goes below the substrate, it rots. The plant grows above the gravel, on hardscape, always.
Several varieties exist: narrow leaf, needle leaf, Windelov (with lacy, branched tips), and Trident. Each has a slightly different texture, making it easy to add variety without adding complexity.
Best for: Low-tech community tanks, betta tanks, tanks with herbivorous fish (Java Fern is one of the few plants goldfish and cichlids won't eat).
2. Anubias (Anubias barteri, Anubias nana, Anubias nana petite)
Difficulty: Beginner | Light: Low to medium | CO₂: Not required
Anubias is the other cornerstone of the low-tech soil-free planted tank. Thick, waxy, deep green leaves that almost nothing will eat. Incredibly slow growth that means it never needs trimming. And a hardiness that makes it almost impossible to kill Anubias will survive temperature swings, neglected water changes, and even weeks without fertilization.
Like Java Fern, it grows from a rhizome that should never be buried. Attach it to hardscape, and it will slowly spread across your aquascape, creating lush green carpets on rock faces and driftwood branches.
Anubias nana petite, the miniature variety, is a particular favourite for aquascapers. Its tiny, perfectly formed leaves bring incredible detail to foreground hardscape. It grows so slowly that a single piece can take months to double in size, but the result is always worth the wait.
One watch-out: Anubias leaves are broad and slow-growing, which makes them a prime target for algae if your tank gets too much light. Keep light moderate and pair with liquid fertilizer to give the plant a competitive edge.
Best for: Aquascaping, shrimp tanks, community tanks, nano setups.
3. Java Moss (Taxiphyllum barbieri)
Difficulty: Beginner | Light: Low to medium | CO₂: Not required
Java Moss is one of the most versatile plants in freshwater aquascaping. It can be tied to rock or driftwood to create lush green mats and carpets. It can be left free-floating as a breeding refuge for fry and shrimp. It can be sandwiched between two mesh sheets to make a moss wall. It can be left to drift and create a wild, naturalistic look.
As we detail in our complete guide to building a moss wall aquascape, Java Moss is the backbone of one of aquascaping's most dramatic effects, and it needs no soil, no CO₂, and minimal light to achieve it.
It's also an excellent biological refuge in a tank. Shrimp graze on the micro-organisms that live within their dense tangles. Fry hide from larger fish. Breeding pairs of certain species will lay eggs directly into Java Moss clumps.
Best for: Moss walls, shrimp tanks, breeding tanks, naturalistic aquascapes, nano tanks.
4. Christmas Moss (Vesicularia montagnei)
Difficulty: Beginner–Intermediate | Light: Low to medium | CO₂: Optional
Christmas Moss gets its name from the way its fronds hang in overlapping layers like the branches of a Christmas tree when viewed up close. It's a step up in elegance from Java Moss, with a more structured, defined texture that works beautifully in aquascaping.
Like Java Moss, it attaches freely to hardscape and can be used for walls, carpets, or tied to branches and rocks. It's slightly more demanding than Java Moss; it benefits from liquid fertilization and grows faster with CO₂, but it's still entirely manageable in a low-tech, no-soil setup.
Best for: Detailed aquascaping, shrimp tanks, mid-to-foreground hardscape.
5. Bucephalandra (Bucephalandra sp.)
Difficulty: Beginner–Intermediate | Light: Low to medium | CO₂: Optional
Bucephalandra "Buce" in the hobby is something of an obsession among serious hobbyists. Native to Borneo, it grows on riverbed rocks and wood in fast-flowing streams. In the aquarium, it attaches to hardscape via rhizome, just like Anubias, and requires no substrate whatsoever.
What sets Buce apart is its extraordinary variety and the iridescent shimmer that wide varieties display under good lighting, blue, green, and purple tones visible in the leaves. There are hundreds of named varieties, ranging from deep emerald green to dark purple with pink spots. Collectors trade rare varieties the way others trade stamps.
It's slow-growing and tolerant of low light, though it responds well to liquid fertilization and will grow faster with CO₂. The flowers' tiny white spathes that occasionally appear underwater are a delightful surprise.
Best for: Detailed aquascaping, collector setups, foreground hardscape, shrimp tanks.
6. Bolbitis (Bolbitis heudelotii)
Difficulty: Intermediate | Light: Low to medium | CO₂: Optional but recommended
Bolbitis, sometimes called the African water fern, is one of the most dramatic-looking plants available in the hobby. Its deep, translucent dark green leaves have a lacy, intricate shape that's unlike anything else in the planted tank world. Under good light, they appear almost black-green, giving a tank a distinctly wild, deep-river quality.
Like Java Fern, it attaches to rock or driftwood via rhizome and must never be buried. It grows slowly but steadily, and tends to look its best in tanks with moderate flow. It was originally adapted to fast-flowing African rivers, and gentle movement helps it show its structure.
It's slightly more demanding than the others on this list; it benefits from liquid fertilization and soft, slightly acidic water but rewards the effort with genuinely stunning results.
Best for: Experienced beginners and intermediate hobbyists, Nature Aquarium and Iwagumi-style scapes, tanks with moderate flow.
7. Hornwort (Ceratophyllum demersum)
Difficulty: Beginner | Light: Low to high | CO₂: Not required
Hornwort is one of the fastest-growing aquarium plants in existence, and one of the best natural water purifiers you can add to a tank. Its feathery, needle-like leaves absorb nitrates and phosphates at a remarkable rate, making it a powerful biological filter supplement, which is exactly why it's a favourite in tanks with heavy fish loads or active breeding.
It can float freely at the surface, be anchored loosely to hardscape, or drift in the mid-water column; it needs no substrate whatsoever. In fact, it has no true roots at all; it absorbs everything it needs directly from the water.
One consideration: because it grows so fast, Hornwort can quickly dominate a tank if not managed. Trim regularly and remove excess growth weekly during the growing season. But for tanks that need fast, effective natural filtration, especially during Indian summer and monsoon when water quality swings are common, it's an invaluable ally.
Best for: Natural filtration, high-bioload tanks, breeding tanks, quarantine tanks.
8. Water Wisteria (Hygrophila difformis)
Difficulty: Beginner | Light: Medium | CO₂: Not required
Water Wisteria is a fast-growing stem plant that can either be planted loosely in gravel (with roots eventually finding their way in) or left free-floating and tied loosely to driftwood; both work. Its delicate, lacy leaves have an almost fern-like texture and create beautiful mid-to-background structure in a tank.
It's a hungry plant that benefits from liquid fertilization and rewards even basic dosing with rapid, lush growth. In strong light, the leaves develop a distinctly golden-green colour. It's also one of the most forgiving plants in the hobby; if you neglect it, it bounces back quickly once conditions improve.
Best for: Background structure, fast-growth tanks, beginner planted tanks, nano tanks.
9. Floating Fern / Water Sprite (Ceratopteris thalictroides)
Difficulty: Beginner | Light: Medium | CO₂: Not required
Water Sprite is one of the most underrated plants in the freshwater hobby. It can grow fully submerged as a mid-water plant or float at the surface with roots dangling below, and in both modes, it provides remarkable benefits to the tank.
Its broad, delicate leaves create surface cover that dimples the light and gives the tank a natural, dappled quality. Its dangling roots provide refuge for shrimp and fry. It absorbs nutrients rapidly, helping control algae. And it's incredibly easy to grow it under moderate light with liquid fertilizer, and it will reward you generously.
Best for: Surface cover, shrimp and fry refuges, natural light diffusion, nano and planted community tanks.
10. Salvinia (Salvinia natans / Salvinia cucullata)
Difficulty: Beginner | Light: Medium to high | CO₂: Not required
Salvinia is a floating fern that lives entirely at the surface, with no roots in the substrate, no attachment to hardscape, just a carpet of small, fuzzy green pads drifting across the water. Under good light, it multiplies quickly and creates a natural canopy that fish like bettas and gouramis absolutely love.
Beyond aesthetics, Salvinia does serious biological work. Its roots pull nutrients directly from the water column, competing aggressively with algae for phosphates and nitrates. A healthy Salvinia cover over a planted tank is one of the most effective natural algae controls available.
The challenge: if it multiplies too fast, it can block light from plants below. Thin it out regularly and consider it a feature rather than a flaw that you always have spare plants to give away.
Best for: Betta tanks, surface cover, natural algae control, paludariums, open-top tanks.
How to Feed Soil-Free Plants
Here's the one thing you do need to make a soil-free planted tank thrive: a good liquid fertilizer.
Root-feeding plants get their macronutrients from the substrate. Soil-free plants get everything from the water column, which means if you're not dosing liquid fertilizer, they're slowly starving. This is the single most common reason epiphyte and floating plant tanks look lackluster despite good light and clean water.
The Sunken Garden Fertilizer range was built specifically for this kind of tank. Each formula delivers both macro and micro nutrients directly into the water column, in an algae-safe, fish-safe, shrimp-safe formulation:
- Sunken Garden Green: the everyday formula for low-tech, non-CO₂ tanks. Perfect for Java Fern, Anubias, Java Moss setups. (from ₹490)
- Sunken Garden Red: for tanks with colour plants like Bucephalandra varieties and red-tinted species. Intensifies pigmentation and strengthens growth.
- Sunken Garden Vibrance: for heavily planted, fast-growing tanks with stem plants and floating species like Hornwort and Water Wisteria. Full Estimative Index dosing.
No soil. No complex multi-bottle routine. Just add to the water, follow the dosage chart, and let your plants grow.

Attaching Plants to Hardscape: A Quick Guide
For epiphytes like Java Fern, Anubias, Buce, and Bolbitis, attachment to hardscape is everything. Three methods work well:
Aquarium-safe superglue (cyanoacrylate gel): The fastest and most reliable method. Apply a small dot of gel to the rock or wood, hold the plant's rhizome in place for 30 seconds, and done. The glue is completely fish and shrimp-safe once cured in water.
Cotton thread or fishing line: Wrap loosely around the rhizome and hardscape a few times and tie off. The plant's roots will grip on their own within 2–4 weeks. Cotton thread will eventually decompose and disappear; fishing line can be removed once the plant has attached.
Plant weights or clips: For stem plants and mosses being placed temporarily, small stainless steel plant weights or mesh clips hold them in position while they establish.
One Last Thing
The best planted tank isn't necessarily the most complex one. Some of the most breathtaking aquascapes in the world are built entirely on Java Fern, Anubias, and a few carefully chosen mosses, with no soil, no CO₂, and no daily maintenance routine. Just clean water, consistent light, and a bottle of liquid fertilizer.
You don't need to choose between a beautiful planted tank and a manageable one. With the right plants, you get both.
