Meet the inhabitants before planning the aquarium
Explore detailed profiles for fish, shrimp and snails, with guidance on identification, habitat, adult size, aquarium space, water conditions, feeding, behaviour and reproduction. The profiles distinguish the needs of different species rather than offering one set of conditions for every animal.
Use the search and category filters to find a familiar common name or a scientific name, then follow the related reading when a comparison helps. The aim is to make your next decision clearer, whether that concerns companions, a feeding routine or the space an adult animal will need.
Turn habitat ideas into practical projects
The expanded collection includes botanical aquascaping projects and guides to paludariums, vivariums and naturalistic terrariums. Explore different approaches to wood, stone, planting, leaf litter, water movement and the transition between water and land.
The projects explain construction and maintenance as well as appearance. Their images help you read the arrangement, while the guidance keeps suitable inhabitants, access and the actual conditions of the setup at the centre of the plan.
Choose materials with a purpose
Our botanical articles explain preparation, tannins, organic load, plant-growing space and the changing surfaces you may notice after introducing natural materials. They are designed to be useful when the aquarium is developing, not just when it is first assembled.
Where a product genuinely fits the subject, contextual links connect the explanation with relevant BBA leaves, pods, wood, foods, support products and botanical boxes. These are choices to assess for your own setup, not a requirement to add everything pictured or buy a complete list.
Free to explore, whenever you need it
All 135 Knowledge Centre materials are publicly available to read without an account. Browse a category, search for a question or species, and keep useful guides close when planning or maintaining your habitat.
