Choose the strength that matches your brief

Aquarium Architecture: Start here when collaboration with your architect or interior designer is central. Its services run from consultation through maintenance, but ask the team to confirm the actual installation and service arrangements at your address.

Aquarium Design International: Compare for a complete design-and-installation brief with worldwide project delivery. Its named U.S. maintenance markets help frame the aftercare conversation; outside those markets, ask whether a service affiliate would be involved.

Tenji: Compare for a public-facing exhibit, fabrication-intensive brief, or renovation. Its portfolio includes institutional settings and its services include installation, repair, and animal care. Ask how those services would be delivered at your property.

Send three companies one brief

Keep the location, intended living system, dimensions, viewing goals, equipment space, and care expectations identical. Ask each company for its proposed team, included services, work assigned to others, and one comparable completed project.

Compare the drawing and handover each firm proposes. A helpful distinction is who owns the design coordination, who delivers the physical installation, and who will care for it once that team leaves.
