75 gallon, comes with the whole setup including 2 90 gallon filters, the light bar with color changing remote. Heaters, and a home made log. This has been setup for less than a year it takes up way too much room in our home and with another baby on the way we need the space way more than the tank. There is a bichir eel in there about 9 inches long, I can rehome or you can keep the eel as well! Very well established tank thats for sure, so sad to have to let it go. Family first.
