380 Gallon Oceanic Aquarium. Oceanic was the “Cadillac” of aquariums prior to recently being bought out by a company that has cheapened the brand! This aquarium was custom built in 2006 at a cost of $10,000. The aquarium has two overflow boxes and has been drilled for plumbing. In great overall condition. This tank is all glass and is very heavy!! Please email me with any questions. I have included some pics of the aquarium. The first is when it was in use. This listing is for Aquarium only no other equipment or livestock.
