DEAN'S FRY SYSTEM AND BEYOND
Speaker: Dean Tweeddale

Dean Tweeddale is a master breeder with over 60 years of experience in the aquarium hobby. He began with guppies, advanced to discus, and has since bred countless species of freshwater fish—virtually any species he could get his hands on. Always an innovator, Dean has, throughout his fishkeeping career, built three in-house fish rooms and developed an incredible fry system. Some of his proudest moments in the hobby are developing a system to raise discus artificially, breeding many rare dwarf cichlids, continuous spawning of German blue rams, and spawning several L-number plecos. He has also collected and bred wild fish from Peru. Dean is a familiar face in the online fishkeeping community, having appeared on numerous YouTube channels including Aquarium Co-Op, Tazawa Tanks, KeepingFishSimple, L.R. Bretz’s Aquatics, Steenfott Aquatics, Swhiskey, Aquarist Podcast, Bentley Pasco, Harlan Ford, Friday Fish Facts, and Dustin’s Fish Tanks. He has also shared his expertise as a featured speaker for aquarium clubs across the country. Dean is passionate about inspiring others to experiment, innovate, and become the best fishkeepers they can be.
