Hello, I am planning to set a 1000 gallon 300x120x100 (cm) tank for my new house. I have couple of questions, what material should the aquarium be or what should be the thickness of the glass? How can I heat the tank effectively? I also plan to have a 250 gallon plastic tank to store water as the regular tap water in Turkey is not good enough. I plan to house two motoro stingrays, one silver arowana and a clown knife. Do you think I can add any other fish? If so what kind?
