Botanicals - Acorn Caps

Acorn caps are excellent, long-lasting natural botanicals for aquariums that release beneficial tannins, lower pH, and provide foraging surfaces for shrimp and micro-habitats for fry. They add aesthetic, natural texture to blackwater and planted tanks while offering hiding spots for bottom-dwellers.

Key Benefits and Uses:

• Water Conditioning & Tannins: As they break down, they release tannins that turn the water a light tea color, which can reduce stress in fish, create a natural blackwater environment, and gently lower pH.
• Biofilm & Feeding: The textured, woody surface of the caps is ideal for beneficial biofilm growth, providing a natural food source for shrimp, snails, and fry.
• Habitat Complexity: They provide small, natural, and aesthetic shelters (hiding spots) for shy fish, invertebrates, and shrimplets.
• Aquascaping: Ideal for creating a “biotope” look, adding a rustic, naturalistic aesthetic to the tank floor.
