The Aquarist’s Edge [Weekly Aquarium Podcast]

Tiger barbs are hardy, colourful, and endlessly entertaining but they’re also one of the most commonly mis-stocked freshwater fish, which is why fin-nipping and “random aggression” show up so often. In this episode of The Aquarist’s Edge, Art breaks down a complete tiger barb care guide: the best tank size in litres, the ideal schooling group size, the most effective ways to reduce aggression, and how to choose tank mates that won’t get harassed.

You’ll also learn practical feeding strategies for health and colour, how to set up your aquascape with sight breaks and swimming lanes, and ways to address and prevent problems like faded colour, chasing, and torn fins.

In this episode of The Aquarist’s Edge, Art explores why the freshwater aquarium hobby needs you. It's not just the experts, not just the big creators, but everyday aquarists who choose patience, good husbandry, and kindness with beginners. You’ll learn how your decisions around aquarium cycling, stocking, quarantine, water testing, and maintenance routines ripple outward to shape fish welfare, local fishkeeping culture, and even what aquarium shops stock. We also unpack how to help new hobbyists without gatekeeping, how to spot and avoid harmful trends, and how to “vote with your wallet” to support ethical fishkeeping.

Whether you keep a single planted tank or a room full of aquariums, this episode will leave you with practical ways to become a positive force in the hobby and improve outcomes for fish in the process.

Algae in freshwater aquariums isn't always a nuisance. It’s a clear signal about lighting, nutrients, plant health, organics, and overall tank stability. In this episode of The Aquarist’s Edge, Art flips the script on aquarium algae and shows you how to “read” what your tank is telling you, identify common algae types (green hair algae, black beard algae, diatoms, green film algae, and cyanobacteria), and reduce algae naturally without wrecking your aquarium balance. You’ll walk away with practical steps to control algae long-term, support healthy plant growth, and keep your aquarium looking great with realistic maintenance.

Art breaks down the real differences between Endler’s livebearers and guppies, going far beyond size and colour. You’ll learn how species genetics, natural behaviour, and evolutionary history shape their health, activity levels, and breeding patterns in the aquarium.

You'll hear about the science behind Endlers’ constant foraging behaviour, why guppies and Endlers hybridise so easily, and how tank design, mineral content, temperature, and feeding strategies directly affect long-term success. Whether you’re keeping Endlers, guppies, or both, this episode provides practical, experience-based advice to help you build stable, thriving livebearer tanks.

This episode exposes one of the most dangerous myths in guppy keeping: that you need perfect water parameters to keep guppies alive. Discover why constant tweaking of pH, hardness, and temperature quietly kills guppies, and learn what these colourful livebearers actually need: stable, mineral-rich water and a calm, consistent routine. Art  breaks down practical guppy care, soft-water strategies, and more.

Whether you’re losing guppies in a new setup or your fancy strains just don’t last, this exploration of guppy water parameters, hard water livebearers, and stable aquarium maintenance will help you turn things around.
