AquaPortail is an aquariums and biology information portal founded in December 2006 by Jean-François Fortier. It promotes modern, responsible, sustainable and environmentally conscious aquarium keeping, combining practical guidance with educational biology resources. Its species guide features 4,640 profiles of aquatic animals and plants from diverse habitats, including 2,650 fish species, and is available in French and Spanish. A biology dictionary explains more than 16,000 terms.

The site supports hobbyists exploring freshwater, cold-water, marine, reef and brackish aquariums, as well as biotope aquariums and aquascaping. Its content covers ornamental fish, aquatic plants, invertebrates, algae and aquarium care, with articles on topics such as feeding fish and maintaining an aquarium. Visitors can also consult manuals, a biology and aquariums blog, calculation tools and a discussion forum. Beyond aquarium keeping, AquaPortail addresses broader subjects in biology, botany and ecology, including ecosystems, habitats and water pollution. Together, these resources serve beginners and experienced enthusiasts seeking reliable information about aquatic life and sustainable aquarium practice.
