Rebecca Bentley is an ichthyologist (Fish Biologist), Fish and reptile keeper and PhD student. Her studies focus on the evolution of Loricariidae (plecos) in the United Kingdom, UK. Rebecca runs the YouTube Channel “Freshwater Ichthyology” which promotes ethical, progressive and scientific advances in Freshwater Fishkeeping. In this episode, we discuss how the aquarium hobby is often sugarcoated as a good example for captive animal care when that isn’t always the, we cover the trap of thinking that just because something is an “ecosystem” or “bio-active” that it is positive or natural and we also cover the morphology of catfish as well as their natural diets.
