India’s no-nonsense school for aquarium science, aquascaping and fishkeeping—built for Indian water, budgets and homes. I’m Mayur Dev, an aquarium educator with 38+ years in the hobby and 20+ professionally. Learn beginner aquarium setup, freshwater fish care, planted aquariums, aquascaping, nitrogen cycle, water chemistry, filtration, nutrition, disease prevention and maintenance for Indian hard water, heat and power cuts. Fish come first: welfare before convenience, décor, trends, views or sales. I investigate fish-food scams, low-quality food and medication, misleading claims and harmful practices. I also question Vastu/luck-based fish purchases and clarify myths when belief compromises fish welfare. We accept no paid brand promotions and disclose any interests. Our purpose is education, not defamation: genuine facts, evidence and experience shared in good faith to improve the hobby and inspire the next generation of responsible fishkeepers. Hindi-first, with simple English.
