In this episode we tackle the six most common, and preventable, mistakes that lead to fish deaths in freshwater aquariums. From skipping the nitrogen cycle to trusting clear water without testing, this episode delivers the science and strategy every beginner aquarist needs.

You’ll learn:

• Why fish die suddenly in new tanks,

• How ammonia poisoning works and how to stop it,

• Why small tanks aren’t easier (and often deadlier),

• How to build habits that support long-term fish health.

Whether you're setting up your first aquarium or fixing mistakes from your last one, this episode is a must-listen for hobbyists who want to do it right.
