How to Plant Aquarium Anubias Right
Anubias is one of those rare aquarium plants that rewards patience more than perfection. If you are figuring out how to plant aquarium anubias, the biggest mistake to avoid is also the most common one - burying the rhizome. Get that one detail right, and Anubias is usually one of the easiest, most reliable plants you can keep in a freshwater tank.
That ease is exactly why so many beginners start with it and why experienced hobbyists still use it in everything from low-tech community tanks to detailed hardscape layouts. It tolerates a wide range of water conditions, handles lower light well, and does not demand CO2 to survive. But easy does not mean indestructible, and proper planting makes the difference between steady growth and a plant that slowly melts away.
How to plant aquarium Anubias without killing it
Anubias does not grow like stem plants or rooted rosette plants. It grows from a thick horizontal structure called a rhizome. The leaves and roots both emerge from that rhizome, and if you bury it under gravel or aquasoil, it can rot. That is why Anubias is usually attached to rock, driftwood, or other hardscape instead of being planted deeply into the substrate.
If your Anubias came potted, in a bunch, or attached to material from a nursery, start by gently removing any rock wool, foam, or wrapping around the roots. Rinse the roots in aquarium-safe water and inspect the plant. Healthy Anubias usually has firm green leaves, pale to medium brown roots, and a solid rhizome that is not mushy.
At that point, you have two good options. You can attach it to hardscape, which is the preferred method for most tanks, or you can place the roots into the substrate while keeping the rhizome fully exposed. Both can work, but attaching it tends to be simpler and safer.
Attaching Anubias to rock or driftwood
This is the most natural way to place Anubias in an aquascape. Set the plant where you want it, with the rhizome resting on the surface of the rock or wood. Then secure it loosely with cotton thread, fishing line, or a small dab of aquarium-safe cyanoacrylate gel glue. You do not want to crush the rhizome. You just want enough contact to keep the plant from floating away.
Over time, the roots will grab onto the surface on their own. Once that happens, thread can be removed if needed, though many hobbyists leave it in place if it is discreet. Cotton thread often breaks down naturally, which makes it convenient for planted tanks.
Driftwood tends to give Anubias a softer, more established look. Rock can make the plant stand out more clearly and is often easier when you want a tight, clean placement in the foreground or midground. Neither is universally better. It depends on the layout you want and how much texture your tank already has.
Can you plant Anubias in substrate?
Yes, but only partly. The roots can go into sand or gravel, but the rhizome must stay above the substrate line. Think of it as anchoring the plant rather than burying it.
This method can work well if you want Anubias tucked near the base of hardscape or integrated into a planted section without visible thread or glue. The trade-off is that it is easier to accidentally cover the rhizome later during maintenance, especially in tanks with active fish, root tabs, or shifting substrate.
Best placement for Anubias in a freshwater tank
Anubias is flexible, but placement still matters. In most aquariums, it works best in the foreground to midground depending on the variety. Smaller types like Anubias nana petite stay compact and fit nicely on small stones or nano driftwood. Larger varieties can anchor the middle of the layout or soften the transition between hardscape and taller plants.
Light is another factor. Anubias prefers low to moderate light. It can survive brighter setups, but that does not mean it loves them. Under strong lighting, especially in slower-growing low-tech tanks, Anubias leaves are magnets for algae. Since the leaves are thick and slow to replace, algae buildup is more than a cosmetic issue. It can linger for a long time.
If your light is intense, place Anubias in shaded areas under wood, behind taller plants, or off to the sides of the tank where the light is less direct. That usually produces cleaner leaves and less frustration.
What to do after planting
Once planted or attached, Anubias does not need much fuss. In fact, too much tinkering is often worse than leaving it alone. It is a slow grower, so visible progress can take time.
Keep water parameters stable and avoid moving the plant repeatedly. Freshly attached Anubias needs time to grip surfaces with its roots. If it keeps coming loose, secure it again rather than forcing it deeper into the substrate.
Fertilization helps, but the approach depends on your setup. Because Anubias feeds partly from the water column, an all-in-one liquid fertilizer is usually more useful than relying only on root tabs. In a very lightly stocked aquarium, nutrient supplementation can make a noticeable difference in leaf color and steady growth. In a well-stocked tank, you may need less than you think.
Liquid carbon is optional, not required. Some hobbyists use it to support low-tech planted tanks and to help with certain algae issues, but Anubias does not need injected CO2 to do well. If you do run CO2, consistent levels matter more than chasing a high number.
Common mistakes when learning how to plant aquarium anubias
The first mistake is burying the rhizome, and it is by far the most damaging. If your plant starts turning mushy at the base or detaching from its leaves, check there first.
The second is placing Anubias under very bright light without enough nutrient balance or plant mass in the tank. Slow growers under harsh light often end up covered in green spot algae, hair algae, or biofilm. This does not always mean the plant is unhealthy, but it does mean the conditions are working against it.
The third is expecting fast growth. Anubias is slow. A healthy plant may produce leaves gradually, not weekly. If the leaves are firm, the rhizome is solid, and the plant is not declining, slow progress is normal.
The fourth is buying more plant than the layout can hold. Some Anubias varieties stay small, while others get broad leaves and a wider footprint. Giving the plant a little room from the start avoids a cramped look later.
How to tell if your Anubias is healthy
Healthy Anubias usually has thick leaves with consistent color, a firm rhizome, and active roots that are holding onto wood, rock, or substrate. New leaves often emerge lighter and darken over time. Occasional older leaf loss is not unusual, especially after shipping or transplanting.
Yellowing can point to nutrient issues, but context matters. One aging leaf is different from widespread pale growth across the plant. Holes, soft spots, or rapid rhizome breakdown usually suggest more serious problems such as rot, damage, or poor planting technique.
If algae is building up only on older leaves, you can trim a few of the worst ones rather than stripping the plant bare. Since Anubias grows slowly, keeping as many healthy leaves as possible helps it recover and continue establishing.
Is Anubias good for beginners?
Absolutely, with one caveat: beginners do best when they understand that Anubias is not a typical rooted plant. Once that clicks, it becomes one of the most forgiving species in freshwater aquariums.
It handles a broad temperature range, works in low-tech setups, and fits a lot of tank styles. It also pairs well with beginner-friendly species like Java fern, mosses, Cryptocoryne, and easy stem plants. For hobbyists building their first planted tank, that flexibility matters. It reduces trial and error while still giving the aquarium a finished, natural look.
For many tanks, Anubias earns its place because it is dependable. That is a big reason it stays popular at every experience level. If you want a plant that can attach to hardscape, tolerate imperfect conditions, and add structure without demanding constant maintenance, it is hard to beat.
Give it a proper start, resist the urge to bury it, and let it settle in. A good Anubias planting job does not look dramatic on day one, but a few weeks later it often looks like it was always meant to be there.
