Why Use Botanicals?

  • Water Chemistry Closer to Where Fish Evolved 

    Tap water is very different from the blackwater rivers and peat swamps many tropical fish come from. As botanicals break down, they release tannins and humic substances that tint the water and, in soft water, gently lower pH, bringing your tank closer to home.

  • Less Stress, More Natural Behavior

    Leaf litter, roots, and tinted water create the shade and cover small tropical fish look for in the wild. With places to hide, shy fish venture out more, schooling fish settle, and colors deepen.

  • Spawning Cues and Breeding Behavior

    In the wild, many fish breed when rains wash leaves into the water and darken it with tannins. A mature botanical tank can send a similar signal, and many keepers see courtship and spawning from fish that never bred in bare tanks.

Inspired by Real Habitats


From Borneo’s peat swamps to the leaf-littered streams of the Amazon, every setup can tell the story of a real place. Our botanicals help you recreate the tannin-stained water, layered structure, and quiet life of the wild habitats your fish come from.

Prepare · Soak · Scape

Every botanical needs a little prep before it goes in your tank. Rinse, boil, and soak until waterlogged. Leaves take minutes, while pods, bark, and roots can take days. Add a few at a time and watch your pH and water clarity. As they soften, botanicals release tannins, grow biofilm, and turn your tank into something closer to the wild.
