looking for sting ray experiences

[reefwars]

they say a blue spot grows to be 9 or 10 inches and needs 150-300 minimum and thats the ray im thinking of getting not sure how hard it is to find but ill deal with that later so i figure ill start with two small ones in a 120 and upgrade to a 300 maybe bigger depending on cost next summer as my final tank and use my 120 for either a sump for another tank or my oscars
