## Resource

In this episode of The Aquarist’s Edge, Art unpacks the mindset behind the title “Don’t Assume You Know” and expose the hidden mistakes that quietly ruin freshwater aquariums. From so-called “beginner fish” and misunderstood nitrogen cycles to tap water assumptions, equipment myths, and misread fish behaviour, learn more about the science and how to stop guessing and start understanding your tank. You’ll learn how to read your fish and plants, how to interpret your water test results properly, and how to build habits that keep your aquarium stable, healthy, and thriving long-term. Whether you’re a new aquarist or you’ve kept tropical fish for years, this episode will help you avoid the silent errors that cost fish lives and money. 🎵Music: Do It All For You (Instrumental) (Epidemic Sound: https://www.epidemicsound.com/music/tracks/a3b90e79-4bae-4989-b0cb-711a0a9b3e47/ )
