: Curators use specialized concrete and resins to "sculpt" artificial coral reefs. These must be durable enough to withstand the salt but textured enough to provide hiding spots for fish and surfaces for beneficial bacteria to grow. The Future of Oceanariums: Sustainability and VR
: Traditional glass is too brittle and heavy for the pressures of an oceanarium. Modern windows are made of polymethyl methacrylate (acrylic), which can be several inches thick yet remain perfectly transparent.
While entertainment remains a primary driver for visitors, modern oceanariums serve three critical pillars:
