• Ideal for tropical fish species such as Discus, Neon Tetras, Dwarf Cichlids, and Catfish.

• Stimulating breeding instincts and enhancing fish vitality.

Benefits and Features

• Natural Protection: Helps prevent fungal infections and egg rot in fish, thanks to the properties of tannins.

• Acidity Regulation: Slightly increases water acidity and helps stabilize pH levels.

• Vital Environment: Contributes to the overall well-being and activity levels of fish and crustaceans.

• Natural Aesthetic: Adds a natural, rustic look to the aquarium floor and serves as an excellent hiding and feeding spot for shrimp.
