So one day I'd like to either have some ID or paroon sharks and I know they require huge tanks to live. I dont have(and likely never will) thousands of dollars to spend on an aquarium so I probably wont ever get any. But are there not cheap big aquariums somewhere? Everywhere I look the 200 gallons+ cost like 3k dollars. So if I ever got a 1000 gallon one would it cost like 20,000$ or could I get cheaper/less decorated ones?
