What They Say
Testimonials

“As someone who has chronic pain, I struggled to keep a Betta fish. Then I discovered the Father Fish method. Now I have several low maintenance aquariums and less pain. I do my best to try to spread this way of fishkeeping worldwide. Come join us on Discord and Facebook and enjoy a community of experienced and helpful fishkeepers from all countries and walks of life.”

“I found that the FF substrate and sand set up has created a natural environment that stabilized the tank so now all the fish are smiling, and the plants are happy. The enjoyment I find in this hobby is because I discovered Father Fish and changed my mindset about what a “Healthy” aquarium is. If you want to avoid a chemical soup of an aquarium, consider the Father Fish method. It’s proven over 60 years by the leader in natural tanks. Now that my pH is steady, all I do is add water weekly and I have not even had to do water changes.”

“I’m from Jakarta, Indonesia. I wanted to express my heartfelt gratitude for your deep substrate method. Before adopting your approach, I faced numerous challenges with my aquarium, and unfortunately, many fish and shrimp didn’t survive. However, since implementing your method, my aquarium has significantly improved. The environment is now healthier, and the fauna within it are thriving. Thank you so much for sharing your knowledge and helping enthusiasts like me create better habitats for our aquatic friends.”
