Epiphytes are the cheat code of aquascaping: plants that grow attached to wood and rock instead of planted in substrate. No planting depth to get wrong, no root tabs, no uprooting disasters — you glue or tie them to hardscape and they take care of the rest. Anubias, java fern, and bucephalandra are the famous trio, but the epiphyte world is bigger and more interesting than that. These are the 11 best epiphyte aquarium plants that never need planting.
What Is an Epiphyte?
In nature, epiphytic aquarium plants grow attached to submerged wood, rocks, and riverbanks — never rooted in soil. They anchor with a thick horizontal rhizome (a stem-like structure) from which leaves grow upward and roots dangle down to grip surfaces. Those dangling roots absorb nutrients directly from the water, which is why epiphytes feed from the water column and couldn't care less about your substrate.
The golden rule: never bury the rhizome. A buried rhizome rots, and rhizome rot kills the plant. Attach epiphytes to hardscape with the rhizome fully exposed to water flow, and they'll thrive for years — many anubias in the hobby are decades old.
How to Attach Epiphytes
Cyanoacrylate superglue (gel)
The fastest method: dab gel superglue on the rhizome or roots, press onto dry-ish wood or rock for 30 seconds, done. It's aquarium-safe once cured (seconds), and the plant grows over the glue spot. Use the gel type — liquid runs everywhere. This is how most aquascapers attach anubias and buce today.
Tie with thread or fishing line
The traditional method: loosely tie the rhizome to wood with cotton thread (dissolves over months) or fishing line (remove later). Don't strangle the rhizome — snug, not tight. Roots will grip the surface within weeks.
Wedge into cracks
The laziest method and often the best: jam the rhizome into a crevice in driftwood or between rocks. No glue, no thread, completely natural. Works beautifully for java fern and anubias nana in textured wood.

The 11 Best Epiphyte Aquarium Plants
1. Anubias barteri var. nana
The most popular aquarium plant in the world for good reason. Anubias nana is nearly indestructible: it tolerates low light, ignores water parameters, grows slowly but forever, and fish leave it alone thanks to tough bitter leaves. Attach to wood or rock; expect a new leaf every few weeks. The "petite" variant stays under 2 inches for nano tanks and foreground hardscape detail.
2. Java Fern (Microsorum pterotoides)
The classic epiphyte — broad green leaves on a creeping rhizome, undemanding and long-lived. Java fern propagates by growing baby plants on the undersides of old leaves; when plantlets develop roots, pluck them off and attach elsewhere. Variants like 'Windelov' (split leaf tips) and 'Trident' (narrow forked leaves) add texture variety. Tough enough for goldfish tanks and cichlid tanks where other plants get eaten.
3. Bucephalandra 'Wavy Green'
Buce (from Borneo) is the connoisseur's epiphyte: small, slow-growing, with waxy leaves that shimmer blue-green to purple under good light. 'Wavy Green' is the hardiest and most affordable variety — a good first buce. All buce grows slowly (patience required) and appreciates stable conditions, but it's no harder than anubias. Keep it shaded; direct bright light invites algae on its slow leaves.
4. Anubias barteri (standard)
The big brother of nana — broad 4-inch leaves on a thick rhizome, growing into an impressive specimen over years. Perfect for large driftwood pieces and cichlid or goldfish tanks where its leathery leaves survive abuse. One of the longest-lived plants you can buy; specimens decades old exist in the hobby.
5. Java Moss (Taxiphyllum barbieri)
Strictly speaking a moss rather than a rhizome plant, but functionally an epiphyte: tie it to wood or rock and it creeps into a lush green carpet of texture. Java moss is the most forgiving moss in the hobby — it grows in almost any conditions, provides fry and shrimp shelter, and propagates by division. Our aquarium moss comparison covers java moss against its fancier cousins.
6. Bolbitis heudelotii (African Water Fern)
A larger, more dramatic fern with translucent dark-green fronds that wave beautifully in current. Bolbitis wants what most epiphytes want — shade, flow, stable water — but is fussier about sudden changes; it may shed leaves when introduced, then regrow adapted foliage. Superb on tall driftwood in larger tanks, where its size (up to 16 inches) makes a statement.
7. Bucephalandra 'Kedagang'
A step up in the buce world: longer, narrower rippled leaves with reddish-brown new growth. Slightly more light-hungry than 'Wavy Green' but still easy by buce standards. Its distinctive leaf shape adds variety to a hardscape planted with rounder anubias. As with all buce, buy from reputable sellers — mislabeled varieties are common.
8. Anubias 'Coffeefolia'
An anubias with deeply puckered, textured leaves that look almost quilted — dramatic texture contrast against smooth-leaved tankmates. Grows larger than nana (6–10 inches), making it a midground hardscape plant. Same bulletproof care as all anubias: attach, shade lightly, ignore.
9. Creeping Jenny? No — Hydrocotyle tripartita (as epiphyte)
Usually grown planted, but Hydrocotyle tripartita also creeps beautifully over wood and rock as a semi-epiphyte, its clover-like leaves cascading down hardscape. Wedge stems into crevices and it spreads into a living waterfall of green. Faster-growing than true rhizome epiphytes, so it fills hardscape quickly — trim regularly to keep it in bounds.
10. Fissidens fontanus (Phoenix Moss)
The most beautiful moss for hardscape: tiny feather-like fronds that grow in neat, slow-spreading patches on wood and rock. Phoenix moss is slower than java moss but far more refined-looking — it doesn't get stringy. Superb for detail work on bonsai-style driftwood trees. Attach with glue; it grips within weeks.
11. Anubias 'Pangolino'
The tiniest anubias — leaves the size of a fingernail on a miniature rhizome. Pangolino is a specialist plant for nano tanks and detailed hardscape work, creating the illusion of scale on small wood pieces. Slow and a bit pricier than nana petite, but unmatched for tiny-scale aquascaping.
Epiphyte Care: The Essentials
Light: less is more
Nearly all epiphytes evolved in shaded forest streams. Moderate to low light keeps them healthy; strong direct light grows algae on their slow leaves faster than the leaves grow. If algae coats your anubias, the fix is usually less light or more shade from floating plants — see our floating plants guide for natural shading options — not more fertilizer.
Feed the water column
Epiphytes eat from the water, so a comprehensive liquid fertilizer is their food. Dose lightly but regularly; they're slow growers with modest appetites. They also appreciate the gentle flow that delivers nutrients to their leaves — position them where the filter current passes, not in dead spots.
Clean the leaves
Slow leaves accumulate biofilm and algae. During water changes, gently brush anubias and fern leaves with a soft toothbrush, or let algae-eating shrimp and otocinclus graze them. A leaf too far gone (covered, melting) should be cut at the rhizome — the plant will replace it.
Watch for rhizome rot
If a rhizome turns brown and mushy, cut away ALL soft tissue back to firm green rhizome, even if that means a tiny fragment remains — firm fragments regrow. Rhizome rot spreads, so act fast. It's almost always caused by burial, physical damage, or prolonged poor water quality.

Designing with Epiphytes
Epiphytes are hardscape plants — think in terms of decorating wood and rock, not filling substrate zones. The classic approach: anubias nana and buce clustered at the base and forks of driftwood, java fern masses on the upper branches, moss softening every joint and edge. This creates the aged, overgrown look that wins aquascaping contests.
Combine epiphytes on hardscape with stem plants in the background and rosettes in the midground for a complete three-layer aquascape where every plant is in its ideal position. Epiphytes also shine in tanks where planting is impossible — bare-bottom breeding tanks, turtle tanks (see plants for turtle tanks), and cichlid setups.
Frequently Asked Questions
Can I just drop anubias in the tank without attaching it?
It'll survive floating or resting on the substrate, but it won't thrive — unattached plants tumble around, get buried, and grow poorly. Attachment takes 30 seconds with superglue gel and transforms results. Even just wedging the rhizome into a crack is enough; the plant does the gripping from there. Tropica's plant database notes which species grow best attached versus planted.
Is superglue really safe for aquariums?
Yes — cyanoacrylate gel is the aquascaping standard and cures inert within seconds underwater. Use plain gel without added fragrances or "antibacterial" claims. Apply outside the tank or with the hardscape briefly lifted out, press for 30 seconds, and it's done. Millions of aquascapes are held together with it.
Why is my java fern growing plantlets on its leaves?
That's reproduction, not disease — java fern grows baby plants on mature leaves, especially when it's happy (or occasionally when stressed). Wait until plantlets have several leaves and visible roots, then gently pluck them off and attach them elsewhere. Free plants, courtesy of your fern.
Do epiphytes need CO2?
No — all the plants on this list thrive without injected CO2. They're slow growers adapted to shaded streams, and their modest metabolism is easily fed by a low-tech tank. CO2 speeds their growth somewhat, but the difference is far less dramatic than with stem plants or carpets. For more no-CO2 options, see our easiest no-CO2 plants.
My anubias leaves are turning yellow — what should I do?
Check the rhizome first: firm and green means a nutrient or light issue; mushy and brown means rhizome rot (cut back to firm tissue immediately). Yellowing on a firm rhizome usually means too much light (move to shade) or a general nutrient shortage (start liquid fertilizer). Old leaves yellowing one at a time is normal aging — remove them at the rhizome.
Can epiphytes grow emersed or in a paludarium?
Many can — anubias, buce, and mosses grow beautifully emersed in humid setups, often flowering. Keep humidity high and the rhizome moist. This is also how most commercial stock is grown, which is why store-bought epiphytes transition to submerged life with minimal melting compared to stem plants.
Never Plant Again (Unless You Want To)
Epiphytes free you from the substrate entirely — glue a rhizome to a beautiful piece of wood, and you have a permanent, evolving decoration that outlives most other plants in the tank. Start with anubias nana and java fern, graduate to buce when you're feeling fancy, and let moss soften every edge. Your hardscape will never look bare again.
