Episode 137: The Environment and Our Bad Behavior

The hosts of Tank Talk dive deep into the complex relationship between fish behavior and environmental responsibility in aquarium keeping. Jason and John challenge the myth that aggression in fish like African cichlids is inherently 'bad'—instead, they argue that behaviors such as fin-flaring, chasing, and lip-locking are normal territorial displays, only crossing into danger when they result in physical damage, prolonged hiding, or inability to eat. They emphasize that species profiles are guidelines, not rules, and that fish can 'go rogue'—a reminder that experience and observation matter more than rigid expectations. On the environmental front, the conversation shifts to the real dangers of irresponsible fish keeping: invasive species like Plecos and Midas cichlids disrupting ecosystems in Florida, and the far more insidious threat of antibiotic resistance spreading from over-the-counter fish treatments to human pathogens. The hosts also tackle misconceptions about water waste, noting that while water use is a valid concern in arid regions, most hobbyists in water-rich areas aren’t the primary culprit—especially when used to nourish gardens. Finally, they reflect on their personal aversion to saltwater aquariums, not due to lack of appreciation for their beauty, but because of the relentless maintenance, emotional toll, and lack of accessible support—highlighting that the hobby’s joy lies in control, predictability, and accessibility, not just aesthetics.
