Give a betta real plants and gentle, shaded cover and you'll usually get a calmer, bolder, better-coloured fish.
Bettas come from shallow, slow-moving water in Southeast Asia — rice paddies, ditches and shaded stream edges thick with vegetation. A bright, bare tank with stiff plastic plants is the opposite of what they're built for.
Live plants quietly do the hard work, too: they soak up the waste that feeds algae, help keep a small tank's water stable, and give your betta places to rest, hide and patrol. Here are five that are genuinely easy, fin-safe and in stock right now.
1. Anubias nana
If you buy a betta just one plant, make it Anubias nana. Its broad, sturdy leaves are exactly the kind of surface a betta loves to drape itself over and sleep on — often right near the top of the tank.
It's also nearly impossible to kill. Anubias grows tied or glued to wood or rock (never buried in the substrate), and it's happy in low light with no CO₂. It grows slowly, so it won't take over.
2. Java Fern
Java Fern gives a betta tank instant structure and shade. Its tall, leathery fronds break up sightlines so a territorial betta feels secure, and create the shady mid-water cover they naturally gravitate towards.
Like Anubias, it attaches to wood or rock rather than going into the substrate, and it shrugs off low light and no-CO₂ setups. Leave it be and it slowly spreads into a lush clump.
3. Amazon Frogbit
Bettas live at the surface — they gulp air from the top, build bubble nests there, and feel exposed under bright, open water. A handful of floating plants changes the whole tank: Amazon Frogbit spreads a canopy of round leaves across the surface, with long roots trailing beneath.
That dappled shade settles a betta, and the dangling roots are a favourite anchor for bubble nests. Frogbit is a hungry feeder too, pulling nitrates straight out of the water to help keep algae down — just thin it out when it spreads too far. On a tighter budget, Salvinia does a similar job from £3.99.
4. Cryptocoryne wendtii
For planted greenery rising from the substrate, Cryptocoryne wendtii is about the most forgiving option there is. It forms a low bush of wavy leaves — green or a deep reddish-brown — that fills the mid-ground and gives a betta cover to weave through.
It's a true low-light, no-CO₂ plant. Don't panic if it drops a few leaves after planting: that's normal ‘crypt melt' as it settles in, and it grows back from the roots within a few weeks.
5. Marimo Moss Balls
If you want live plants with nothing at all to learn, drop in a couple of Marimo moss balls. They sit on the substrate, need no planting, no CO₂ and barely any light, and slowly soak up nutrients as they go.
Bettas often nudge and rest against them, and they're a tidy way to add a bit of green to a nano betta tank without committing to a full scape.

| Plant | Position | Light | CO₂ | Best for |
|---|---|---|---|---|
| Anubias nana | On wood/rock | Low | No | Resting leaves |
| Java Fern | On wood/rock | Low | No | Shade & cover |
| Amazon Frogbit | Floating | Low–bright | No | Surface cover |
| Cryptocoryne wendtii | In substrate | Low | No | Rooted greenery |
| Marimo Moss Balls | On substrate | Low | No | Zero effort |
Setting it up
Attach the Anubias and Java Fern to wood or rock with cotton thread or a dab of gel glue — don't bury their roots, or they'll rot. Plant the Cryptocoryne in the substrate, float the Frogbit on top, and simply drop the moss balls on the floor. Keep the lighting modest and the filter flow gentle: bettas hate being pushed around, and all five plants prefer calm water.
A few things worth remembering:
- Add floating cover first — surface shade settles a betta faster than anything.
- Attach the Anubias and Java Fern; don't bury the rhizome, or it rots.
- Keep the flow gentle — bettas hate being pushed around.
- Expect a little crypt melt at first; it regrows from the roots.
