FeaturedPrice on InquiryKey Aspects of the Father Fish Method: Deep Substrate: Uses a "dirted" tank approach, often recommending a bottom layer of soil topped with sand (often called Aqua Preta) to create a nutrient-rich, living substrate. Minimal Intervention: Minimizes the need for mechanical filtration, chemical additives, and frequent water changes, relying instead on biological processes. Natural Ecosystem: Focuses on dense planting and utilizing microorganisms (like scuds) to create a self-sustaining environment that mimics nature. "Old School" Approach: Draws on traditional, long-term fishkeeping techniques developed over 25+ years.
