OCTANE Habitat Supplies for the Botanical Method, Blackwater, and Biotope Aquarium

Every product we have ever made at Betta Botanicals has been built around one principle: accurate habitat replication.

We source Catappa leaves because Terminalia catappa drops into the water column in the blackwater habitats across Southeast Asia. We source jackfruit, sterculia pods, oak twigs, and alder cones because these materials enter aquatic ecosystems through natural seasonal cycles — floods, wind, decomposition. As nature intended. That is the method.

So today, we are proud to introduce OCTANE.

OCTANE is our most accurate habitat replication collection yet. Reflecting the actual state of many of the world's most biodiverse freshwater systems, right now, in real time.

The Product Line

Oil Sheen is an allochthonous surface input. It arrives from land, from industry, from agriculture. In the Mekong Delta, in tributaries of the Amazon, in blackwater streams across Borneo, it is present. If you want your aquarium to reflect what actually sits on the surface of tropical waterways today, nothing is more accurate.

Microplastic Substrate functions as a fine particulate substrate additive. High durability. Virtually no decomposition rate — which is ecologically significant when you consider that standard microplastic particles can persist in aquatic environments for hundreds of years. Microplastic contamination has been documented in fish across Amazonian stream systems, including species from the same families commonly collected for the aquarium trade.

Sawdust Silt is a fine organic particulate sourced from active deforestation zones. The Amazon loses an estimated 10,000 square kilometers of forest per year — much of that material, the fine dust and debris from logging operations, enters local waterways as sediment. This product sources directly from those sites and is made up of tree species from your fishes native habitat.

The Plastic Bag is a structural hardscape element. Macroplastic. Permanent feature. In flooded forest systems from Indonesia to Brazil, plastic bags are now part of the habitat structure. Fish shelter beneath them. Invertebrates colonize their surfaces. They are not going anywhere.

The Plastic Bottle functions as a synthetic cave. Macroplastic. Permanent feature. Hollow, buoyant, and structurally durable — it provides refuge spaces that, in heavily impacted waterways, have become part of the actual habitat matrix.

April Fools! Unfortunately, the occurrence of the above isn't.

OCTANE is not real. The pollution is.

We built this because accurate habitat replication requires honesty about what those habitats actually look like. The rivers we reference — the blackwater tributaries of the Amazon, the peat swamp forest streams of Borneo, the hill streams of the Mekong — are under pressure that most aquarium hobby content does not acknowledge.

Below you will find a short curated list of organizations conducting conservation work in these habitats where many of our popular aquarium fish are sourced from.

Aquatic Organizations Worth Your Attention

Project Piaba works in the Rio Negro basin to support sustainable wild-caught ornamental fisheries as a conservation mechanism. "Buy a fish, save a tree" is a documented economic model that connects the aquarium hobby directly to the standing forests.

Parosphromenus Indonesia is a Jakarta-based NGO working on in-situ conservation of licorice gouramis — blackwater specialists found in Indonesia's peat swamp forests and marsh systems. The organization works directly with local communities to protect and restore habitat, monitor ecosystems, and build the knowledge base needed to keep these species viable in the wild.

SHOAL is a freshwater fish conservation coalition working across multiple basins to address the global extinction crisis in freshwater biodiversity. Freshwater fish are disappearing at rates that exceed most terrestrial vertebrates. SHOAL is one of the few organizations treating this as the emergency it is.

OCTANE drops today.

The rest is up to you.

Betta Botanicals supports the Botanical Method Aquarium — a methodology grounded in ecology, patience, and natural process. Our products are packaged in home-compostable materials. We regularly hold fundraisers supporting conservation organizations working in the habitats we reference.
