Using Aquaryus well

Compare before choosing

Aquaryus is designed as a practical encyclopedia: each profile helps you check the real needs of a species before adding it to an aquarium. Start with the scientific or common name, then compare adult size, minimum volume, temperature, pH and water type.

To avoid poor choices, continue to families, related species and useful guides. This path turns a simple search into a safer decision for living animals and plants.
