The 500 gallon fish tank is ideal for holding as many as seven Oscar fish as they require more space to feed and live their future lives. A 500 gallon fish tank is also suitable for building a large reef tank containing many corals. There is no sight as attractive as watching fish swim about inside an aquarium and the 500 gallon fish tank is no exception. It may not always be suitable for homes, given its big size and so, some interesting 500 gallon fish tanks may be found in places such as Marine Centers.
The Hatfield Marine Science Center has recently acquired a 500 gallon fish tank that is also equipped with a semi-closed circulation system, and a fluidized bed-filter as well as protein skimmer to keep the water pristine clear all year round. The first of its inhabitants were the adult sablefish that came replete with PIT tags, which are devices used by researchers to track fish in propulsion systems by identifying and tracking them with the help of these PIT tags.
The beauty of the PIT tags is that the visitor to the Marine Center can scan individual fish when it comes to the front of the aquarium and this scanning, with the help of a radio wave, enables the PIT tag to create a characteristic frequency that is the result of an inductive process and the signal in turn is used to cue a computer to display the relevant video program. These video programs are 90 seconds that consist of highlighting different aspects of the research done by NOAA into the sablefish life history and population dynamics.
The 500 gallon fish tank is not a common fish tank and of those that are found may have certain characteristics such as being divided into two halves - one for the reef and one for predators. The flow of water is surged into the center of the 500 gallon fish tank from where it is transformed into a wave that travels through both sections. The treatment of the 500 gallon fish tank is through the Model 24 Eco-Wheel system and is able to run off of one air pump.
There is a beautiful 500 gallon 'L' Shaped In-Wall Marine fish tank available at Aquarium Design, which stands 40" tall and is 30/24" inches wide, and its length is 95/46" made out of Acrylic with a bent corner for placement in-wall and it has a port hole on the third side. It uses wet-dry-filter for filtration purposes. It has a pump for filer circulation and one for internal circulation and is also well lit using four 250 wt. 55K Metal Halides, as well as four 40 wt. fluorescents.
