Anubias Sizes Compared: Nana Petite vs Frazeri vs Hastifolia

Anubias is arguably the most bulletproof plant in the hobby — it tolerates low light, survives nibbling fish, and grows on wood and rock where other plants fail. But buy the wrong size and your aquascape's proportions fall apart overnight. Here is how the three most popular varieties compare, and how to place each one.

Key takeaways

  • Size is everything with Anubias: Nana Petite suits nano tanks, Frazeri fits 20–29 gallons, Hastifolia needs 55 gallons or more.
  • Never bury the rhizome — it rots. Tie or glue Anubias to wood or rock instead.
  • Slow growers plus bright light equals an algae magnet, so keep Anubias shaded.
  • Frazeri's thick rhizome survives cichlids and goldfish that destroy delicate plants.
  • Mixing sizes (Petite foreground, Frazeri mid-ground, large background) builds natural depth.

Three Anubias Sizes at a Glance

Variety Leaf size Best tank size Placement
Nana Petite Thumbnail-sized Nano tanks, desktop shrimp bowls Tucked into hardscape crevices
Frazeri Large Long, narrow, elegant 20–29 gallon standard Mid-ground focal point
Hastifolia Massive, spear-shaped 55 gallons and up Background, can grow emersed

Nana Petite: The Nano Detailer

If you keep a nano tank or a desktop shrimp setup, Anubias Nana Petite is the detail plant. Its leaves rarely grow bigger than a thumbnail, so you can wedge it into dragon stone crevices or glue it to the tips of spider wood. The effect is a weathered, ancient look that shows off the hardscape instead of hiding it.

One warning: because it is small and slow-growing, it collects green spot algae quickly under high light. Keep it shaded under taller plants or hardscape overhangs, and it will stay clean and compact.

Frazeri Large: The Mid-Ground Sweet Spot

Frazeri Large — a hybrid of Anubias barteri and Anubias congensis — is the classic jungle plant for a standard 20- or 29-gallon tank. Its long, narrow leaves on elegant stems are big enough to anchor a scape as a mid-ground focal point tied to a central piece of driftwood, without blocking light from the foreground.

It is also the answer to destructive fish. If your cichlids or goldfish uproot every delicate stem plant, a thick Frazeri rhizome glued to a heavy rock is practically indestructible — they can tug at it all day and it will not budge. That toughness is why Anubias pairs so well with other driftwood epiphytes like Bucephalandra in a low-maintenance layout.

Hastifolia: The Background Giant

Do not put Hastifolia in a 10-gallon tank. This is a beast of a plant, with massive spear-shaped leaves on very long stems that look like they belong in a dinosaur film. In a 55-gallon or larger tank, though, it is the ultimate background epiphyte.

In an open-top tank its leaves will happily break the surface and keep growing emersed, giving a wild, overflowing jungle look. Like all Anubias it must be attached to hardscape rather than buried, and it tolerates the same rough treatment from big fish that makes the whole genus so hobbyist-friendly.

Care Rules for Every Anubias

The golden rule comes first: never bury the thick, green, horizontal rhizome in gravel or aquasoil — it rots into mush. Tie it to wood or stone, or glue it with a few dabs of aquarium-safe cyanoacrylate gel, and let the thinner white roots find their own way down. Cotton thread also works; it rots away naturally once roots grip.

The second rule is shade. These are slow growers, and bright direct light turns them into expensive algae farms — tuck them beneath taller background plants.

If leaf edges turn black and fuzzy, that is usually black beard algae: cut the lighting hours or move the plant to a dimmer spot. Our algae identification guide helps you confirm the type before treating.

Tip: when you buy Anubias, check the rhizome first — firm and green means healthy, soft or mushy means rot has already started. A healthy rhizome is the whole plant's future, and it will probably outlive the tank itself.

Anubias FAQ

Which Anubias fits a 10-gallon tank?

Nana Petite — its thumbnail-sized leaves stay proportional to a small footprint, while Frazeri and Hastifolia will quickly overwhelm a tank that size.

Can I mix several Anubias sizes in one tank?

Yes, and it often looks better than a single variety: Nana Petite for foreground detail, Frazeri as the mid-ground anchor, and a larger variety in the background creates natural depth in one aquascape. Getting scale right is half of aquascaping — see our aquascaping tips for more on proportion.

Picking the right Anubias is not about which one looks coolest in a stock photo — it is about scale. Match the plant to your tank, keep the rhizome breathing above the substrate, and give it shade, and you will have a green centerpiece for years. At CozyWoodLab, our driftwood is shaped to show off epiphytes exactly like this: branching pieces with crevices and tips where a Nana Petite or a Frazeri can grip and grow.
