Bajakah Root | Spatholobus littoralis hassk
Red & Yellow Bajakah Root on the Surface:
Red and Yellow Bajakah Root comes from Spatholobus littoralis hassk, a climbing woody vine native to the lowland rainforests of Borneo and Kalimantan, Indonesia, where bettas, rasboras, gouramis, and other popular aquarium fishes can be found. This dense, fibrous rootwood contains naturally occurring phenolic compounds and tannins that contribute a yellow and reddish-amber tint, which is characteristic of blackwater habitats in this region. In the botanical method, blackwater, and biotope aquarium, and bioactive enclosure, Bajakah Root releases beneficial compounds and adds substrate complexity as we would find in nature. There is extensive research into the benefits of this wood for human health, and we can only assume some of these benefits could contribute to a more ideal habitat for our shrimp, isopods, and fishes.

Red & Yellow Bajakah Root for Aquariums & Vivariums
Red and Yellow Bajakah Root contribute both chemical inputs and physical structure to the botanical method aquarium. As it conditions, the fibrous surfaces serve as durable sites for microbial and fungal colonization, encouraging biofilms that are natural grazing surfaces for shrimp, snails, and other microfauna. These microbial films form foundational food web support, a layer of the food chain missing from most conventional aquariums.
Chemically, the rootwood releases tannins, humic substances, and phenolic compounds gradually into the water column. These dissolved organics help replicate the slow allochthonous inputs found in natural blackwater rivers and flooded forests, where fallen wood and bark continuously leach substances that influence water chemistry and habitat complexity.
Because Bajakah Root breaks down slowly, it remains a persistent habitat element rather than quickly cycling into fine detritus like some leaves. The rough, irregular texture supports biofilm development over long timeframes, making it particularly valuable in setups where stable microbial surfaces and substrate complexity are desired.
Bajakah Root can be placed directly into the aquarium, or pre-conditioned outside the ecosystem to moderate early tannin release, especially in smaller tanks where chemical shifts are more pronounced. In larger aquariums, multiple pieces can be combined with leaves, pods, and twigs to build an ecologically rich “perpetual substrate” that encourages natural behaviors and supports long-term ecosystem processes.
In bioactive enclosures, Bajakah Root serves as a durable element of the leaf litter bed, retaining humidity and mimicking the range of textures we would witness in nature. Placed among softer botanicals and soil, it supports isopods and springtails, and the fungal and microbial networks helping to break down and contribute carbon-rich material back into the soil food web over time.
Beneath the Leaves: Spatholobus littoralis in the Wild
In the rainforests of Borneo and Kalimantan, Spatholobus littoralis hassk grows as a woody vine whose roots and stems intertwine with forest soil and understory vegetation. When woody debris from the trees and vines enters waterways or falls into shaded areas, it's colonized by fungi, bacteria, and eaten by detritivores that break down this botanical. This process releases tannins and dissolved organic matter gradually, shaping the water chemistry and microbial communities in ways that support diverse biological activity.
What makes Spatholobus littoralis particularly notable is the growing body of phytochemical research focused on its wood, stems, and roots. Laboratory analyses have documented high concentrations of phenolic compounds, including flavonoids, tannins, and related antioxidants. These compounds are understood to play defensive and regulatory roles in the plant itself, influencing microbial growth, oxidative processes, and decomposition pathways. While much of this research originates from ethnobotanical and pharmaceutical contexts, the chemical profiles are well established at the material level.
Sustainability Note:
This product’s packaging is home compostable.
Just like the botanicals inside, it will break down naturally and return to the soil, because what supports your ecosystem should minimally impact our planet.
Not for human consumption. Preparation not required.
This is a natural product. Variation in color, shape, and texture is expected.

Home is getting more natural
While the aesthetic appeal of botanicals and tinted water can be quite attractive to us, the recreation of nature to emulate water conditions, feeding patterns, spawning displays, and territory building are the true benefits botanicals provide to our critters.
Botanical FAQs
Compostable Packaging Promise
Our packaging is designed to return safely to the Earth, just like the botanicals inside. Every bag is BPA- and Phthalate-free, GMO-free, and contains no animal products. Each meets ASTM D6400 composting standards, ensuring it can fully break down in a home compost bin.
What are the Fluffy White Growths on my Botanicals?
That’s biofilm and fungi—what we call the “goo phase.” It’s one of the clearest signs that your aquarium is alive and functioning. These growths wax and wane naturally as botanicals decompose. They’re harmless, even beneficial, and will disappear on their own once microbial populations stabilize.
Will botanicals lower the pH of my water?
That depends entirely on your source water. In very soft or RODI water, botanicals can gradually lower pH as tannins and humic substances accumulate. In medium to hard tap water, buffering capacity often resists these shifts, and you may not notice much change. At Betta Botanicals HQ, our very hard water (350+ ppm) shows almost no pH change unless we use botanicals like Alder Cones or Macaranga Leaves.
When should I replace leaves or pods in my tank?
We recommend allowing botanicals to fully break down into detritus, since this fuels microbial life and enriches the substrate. You can remove them once they stop tinting the water, but you’ll lose some of their ecological benefits. Each time you add new botanicals, follow proper preparation and observe your livestock until you learn your aquarium’s rhythm.
Are your products just for bettas?
Nope. Our botanicals are safe for almost all aquariums, terrariums, vivariums, and paludariums. The only exceptions are goldfish and axolotls, which may ingest small pods like alder cones or casuarina cones. For those species, we recommend large leaves such as Indian Almond, Loquat, or Jackfruit.
What are Tannins?
Tannins are natural compounds released by leaves, seed pods, and bark as they decompose in water. They soften water, gently lower pH, and create the characteristic tea-stained tint found in blackwater habitats. But their role goes far beyond color—tannins fuel beneficial bacteria, fungi, and biofilms, which form the foundation of a healthy ecosystem. They also offer mild antifungal benefits and help reduce stress in fish by replicating the natural conditions they’ve evolved in. At their core, tannins are plant-derived antioxidants that connect your aquarium to the same processes at work in wild flooded forests and streams.
