World Fish Guide is an educational site focused on beautiful ornamental aquarium fish from around the world. Our goal is to help beginners choose fish responsibly, understand basic care needs, and build healthier aquariums.
Start on the homepage to browse categories, or open All Guides to see the complete list of posts. Each profile is written for general hobbyist learning and may vary by local conditions and individual fish.
Aquarium success depends on many factors—tank maturity, filtration, stocking level, water parameters, and individual behavior. If something seems uncertain or varies by location, we’ll say so directly.
