I got into keeping saltwater fish after seeing the blue spotted ray I have, it's a round one, still thinking about getting a 2nd one. My tank is 475 gallon 8ft long, 3ft wide, 36? Inch high. With liverock off to one side. Gotta go back to work so laters
I have had my blue spotted stingray for over a year now. I think 180 gallon should be the min, and haven that be. 80% sand bed. Mine seems happy. My tank is 400 gallon I think.
