Marine fish tanks refer to vivaria/enclosures which provide an optimal environment for survival of fish and aquatic plants such as planktons and are quite distinctive from ordinary fish aquaria in the sense that they provide a conducive habitat for salty/saline water fish species. The two main types of marine fish tanks, temperate and tropical, have unique architectures and equipment which make them ideal for raring a wide range of fish species in limited space.
Unlike ordinary fish tanks, marine fish tanks often use chemical and mechanical infiltration to provide conducive and enabling environments for growth and reproduction of saline water fish, as suggested by Lucas, Southgate, and Tucker (2019). Moreover, the tanks may contain a live rock, coral reef builder, which provides nitrogen in the water and calcium carbonate needed by the fish. The solute concentration in saline water tanks is controlled and continuously balanced to ensure environmental equilibrium required by various fish species and subspecies.

Tropical and temperate saline water fish tanks are the two main types of fish tanks which provide different conditions that enable different species of fish to survive in the enclosures. Temperate saline water fish tanks house colorful fish species such as anemones and ornate found in West Pacific Coast at temperatures ranging between 10°C to approximately 24°C (Ferris, 2019). Tropical saline water tanks, on the other hand, operates at temperatures between 24°C and 29°C to host fish species from temperate climates (Ferris, 2019).
Both types of saline water fish tanks have sophisticated architecture and equipment which provide conditioned environments for the fish. They both have lighting equipment, heating systems, water filtration system equipment. The walls of the tanks are made up of acrylic (or glass) shielding which protects the water from environmental interference. In conclusion, marine fish tanks are unique and efficient in housing a wide range of saline water fish species.
