Best Epiphyte Aquarium Plants for Betta Tanks
As an Amazon Associate we earn from qualifying purchases.
Epiphyte aquarium plants are the kind that grow attached to wood or rock instead of rooting in the substrate, and the honest first thing to say about this roundup is that the product listings available for it are lights, not plants. None of the listings below sells an epiphyte. What they do cover is the lighting that any planted betta tank depends on, so this page compares eight lights by what their listings state: size, wattage, mounting, timers and waterproofing. If you are about to put plants in a small tank, the light is the part of the setup you will want to get right first.
Quick answer
- Tank under 3 gallons: the AREPK light listed for under 3 gallon tanks, with a gooseneck, a timer and USB power.
- Tank under 7 gallons: the larger AREPK, with the same features.
- Planted-tank control: the Fluval Plant 3.0 lists a programmable 24-hour cycle with sunrise, midday, sunset and night settings.
- Submersible accent lighting: the iKefe lights are listed as IP68 and usable underwater.
- Large tank, 48 to 60 inches: the KZKR foldable hood lamp is the only one here sized that long.
What this page covers, and what it does not
The listings here do not describe any live plant, so the page makes no claims about how any particular epiphyte grows, how much light it needs, or how to attach it. Where a listing says its light helps plants grow, that is the maker’s statement and is reported as such. For plant choices that suit a betta tank, see our guide to aquarium plants for a betta tank.
The reason to look at lights anyway is simple: plants of every kind sit in the same tank as the fish, and the light you choose decides the day and night rhythm, how much heat the lamp adds, and how much room is left on top of the tank. Those are practical points a listing can answer.
How to read a light listing
Size and mounting
Start with the physical fit. A tabletop gooseneck lamp stands on a board beside or over the tank. A hood lamp spans the top. A surface-mount submersible strip is stuck inside with suction cups. A mounting type that does not suit your tank is the most common reason a light does not work out, so check this before wattage.
Wattage and spectrum
Wattage tells you how much electricity the light uses, not how bright it is for a plant. Spectrum claims such as full spectrum are the maker’s description. Several of the listings mention color temperature figures, such as 6000K for the bamboo-board lamps and 7000-7500K white with 460nm blue for the iKefe white and blue strips. Use these as comparison points between listings, and not as a guarantee about plant growth.
Waterproofing
The listings disagree on this, so read it closely. The KZKR hood lamp says plainly that it is not waterproof and must not go in the water. The iKefe strips are listed as IP68 and submersible. The bamboo-board lamps are listed as waterproof in the spec table, though the bullets describe the board rather than the lamp head as waterproof, so treat the lamp head as a fixture that belongs above the water.
Timers and control
A timer matters in a small tank because it keeps the light cycle steady without your remembering to switch it. The AREPK lamps and the iKefe white and blue strips list timers. The Fluval Plant 3.0 lists a programmable 24-hour cycle. The KZKR lists three control modes with a remote.

The picks
AREPK Aquarium and Terrarium Light, for under 3 gallon tanks
This is the smallest-tank option on the page. The listing describes a full spectrum LED lamp for aquarium, betta tank, plant growth and miniature landscapes, with a 6000K color temperature, a timer that turns the light on and off, and a flexible gooseneck that turns 360 degrees. It stands on a bamboo board and runs from a 50-inch USB cord, so a laptop, desktop or power bank can power it. The listing gives 5 watts, 9 x 8.6 x 15.7 inches and about 0.89 kg, and a 5V 1A adapter with a US two-pin plug is included along with 6 clear adhesive bumper pads and a manual. A 1-year warranty is listed for the larger AREPK; for this one the specs list none.
It suits a desk-size betta tank, a bowl or a small moss setup. Its limit is the stated size: it is sold for under 3 gallons.
AREPK Aquarium and Terrarium Light, for under 7 gallon tanks
The same design in a larger size. The listing says this version is for tanks under 7 gallons and gives 9 watts, 13 x 13.3 x 21.5 inches and a 5V supply, with the timer, 360 degree gooseneck, bamboo board and USB cord. It lists a 1-year warranty. The listing again names betta tanks, moss, mosses on landscapes and small tanks of various shapes.
Pick it when your tank is a little roomier and you want the same simple lamp. The extra wattage and height come with a larger footprint on the desk.
HIRO AQUATICS Full Spectrum LED Light with Bamboo Board
This lamp is sold for nano tanks, betta tanks, potted plants, succulents and miniature landscapes, and it can also work as a desk light. The listing gives 5 watts, 6000K, CRI above 80, 100-240V and a US two-pin plug. The bamboo board is 8.5 x 9 inches and is described as waterproof and insulated, and it can hold a lamp height up to 18 inches. The lamp swivels 360 degrees, and each bead has a lens meant to widen the illumination. It weighs 2 pounds and has a one-year manufacturer warranty plus lifetime tech support.
It fits someone who wants one lamp for a nano tank and a houseplant. The listing does not state a timer, so you would use a plug-in timer if you want automatic cycles.
Fluval Plant 3.0 LED Planted Aquarium Lighting, 22 Watts
This is the planted-tank specialist. The listing describes programmable, gradual 24-hour light cycle settings with sunrise, midday, sunset and night, six band waves for full spectrum results, optional pre-set habitat configurations (Lake Malawi, Tropical and Planted), 120 degree light dispersion and extendable mounting brackets for a range of aquarium widths. It is rated at 22 watts, covers 15 to 24 inches, measures 2.5 x 15 x 0.63 inches and weighs 0.55 kg. A 3 year limited warranty is listed.
It suits a tank in the 15 to 24 inch range where you want control of the light cycle. It will not fit a tank outside that width, so measure the rim before you buy.
iKefe 7.5″ Color Changing LED Submersible Light
This is the accent light of the group. The listing says it meets the IP68 waterproof standard and can be used underwater in salt water or freshwater, mounts on smooth surfaces such as a tank cover or background, and works with a wireless or wired remote. It offers 16 colors and four transition effects (flash, strobe, fade, smooth). The listing also calls it dimmable full spectrum RGB suited to plants and fish, powered by 12V low voltage. It is 3 watts, 7.52 inches long and weighs 196 g.
It suits someone who wants color effects and an underwater light. If your main need is a plant-growth light, the listing language is more about decoration than horticulture, so consider it as a supplement.
iKefe 7.5″ White and Blue Submersible Aquarium Light
The white and blue version trades color effects for a timer. The listing describes three lighting modes (blue, white or both), a built-in programmable timer with 6, 10 or 12 hour options, individually adjustable brightness for the white and blue, 7000-7500K white LEDs and 460nm blue, IP68 waterproofing and a suction cup mount. It is powered at 12V low voltage and the listing promises a free replacement for a quality problem within a year. Listed at 3 watts, 9.06 x 3.15 x 1.77 inches and 0.19 kg.
It fits a small tank where you want a self-timing light tucked inside. The listing names the light as usable as a main light, accent light or replacement hood light.
iKefe 15″ White and Blue Submersible Aquarium Light
The same feature set in a longer body for a wider tank. The listing gives 7 watts, 15 x 2 x 2 inches and 212 g, two suction cups, a power adapter and a one-year warranty. The 15 inch length suits tanks that are a bit wider; the listing does not say what tank sizes it covers, so compare its length to your tank’s interior.
KZKR Foldable Aquarium Hood Lamp, 48 to 60 inch
This is the only large-tank light in the set. It is two 22.5 inch lights joined with retractable brackets to suit tanks 48 to 60 inches long. The listing gives 5355 lumens, about 34 watts, 153 light sources and a full spectrum description, with three modes (all LEDs, only blue LEDs, or off) and a remote. It is explicitly not waterproof, has a foldable design to reduce transit damage, and carries a 2 year warranty. The package contains the light, two extendable brackets and a power supply.
It is not a betta-bowl light. Choose it only for a long tank, and keep it above the water.
Which light for which tank
Match the lamp to the tank, then to the control you want. A desk bowl or nano tank points to the AREPK or HIRO tabletop lamps. A tank where you want a day and night rhythm points to the Fluval or to a lamp with a timer. A long tank needs a long light. If you want a light inside the tank, the iKefe strips are the ones whose listings say they are submersible.
Remember also that a light is one part of a plant setup. Your freshwater LED grow light comparison covers more options for planted tanks.
Common mistakes to avoid
- Putting a non-waterproof lamp where it can be splashed or submerged. The KZKR listing warns against it.
- Buying a long light for a short tank, or the reverse. Measure first.
- Treating the maker’s full spectrum claim as proof of plant growth. It is a description.
- Skipping a timer. Without one, the light cycle depends on your habits.
- Forgetting the cord. The AREPK lists a 50-inch USB cord; check that your outlet or port is within reach.
FAQ
Are any of these listings actual epiphyte plants?
No. All eight are lights. The page covers lighting because plants of any kind depend on it.
Which light has a timer?
The AREPK lamps list a timer that switches the light on and off, and the iKefe white and blue strips list 6, 10 and 12 hour options. The Fluval lists a programmable 24-hour cycle.
Which lights can go underwater?
The iKefe lights are listed as IP68 and submersible. The KZKR is listed as not waterproof.
What size tank is the Fluval Plant 3.0 for?
The listing gives a range of 15 to 24 inches, with extendable brackets for a range of aquarium widths.
Which light is best for a bowl?
The AREPK sized for under 3 gallons is the one whose listing states the smallest tank size.
Can a light make my fish sick?
Listings do not address fish health. If your betta seems unwell, ask a vet who treats fish.
Bottom line
Pick the light by tank size first: AREPK for the smallest tanks, Fluval Plant 3.0 for tanks 15 to 24 inches where you want a programmed day, iKefe if you want a submersible strip, and KZKR only for a long tank. For help choosing plants, start with plants that do well in sand and plants suited to a betta tank.
