Naveen Pandurangavittal
Hi, I'm Naveen Pandurangavittal, founder of Exotic Fish Hub. My fishkeeping hobby started in 1993 when I was 11 years old. I still remember when my parents bought me a small aquarium along with a pair of black mollies, white mollies, yellow mollies, guppies, zebra danios, a tiny goldfish, and all the accessories needed to get started. It was the first time in my life that I had seen such colorful fish, and as an 11-year-old kid, I was completely fascinated by them from the moment I saw them. What started as a simple gift soon became a lifelong passion. With 30+ years of fishkeeping experience, I have kept and bred freshwater fish in aquariums, cement tanks, and outdoor ponds. Over the years, I've kept a wide variety of species including guppies, mollies, goldfish, discus, angelfish, bettas, tetras, cichlids, Thai orandas, ranchus, pearlscales, and many others. I've also spent years experimenting with planted aquariums, fancy guppy strains, aquatic plants, and different aquarium setups. Even today, I continue to be fascinated by the beauty, behavior, and diversity of aquarium fish. Through Exotic Fish Hub, I share practical fishkeeping knowledge, breeding tips, aquarium setup advice, and solutions to common fish care problems based on real-world experience to help fellow hobbyists build healthier, thriving aquariums.
