How many stingrays can work in a 8x3 tank?

[Crazyfish88]

Hey everyone just wondering how many rays could I place in my 450 gallon 8x3x2.5 tank? I currently have a pair of 9"-12" marbles in my tank and wanting to add 1 or 2 more at 11"-12". I'm also down sizing the current stock in my 450g to reduce the bio load for the rays.

I think three adult rays in that tank would be an easy bio load to keep up with.

Ya the bio load I'm not too worried about it. My filtration should handle it. Running a 100 gallon sump+ a fx5 and I do 70% wc once a week. I looking at a beautiful pair of rays locally at a good price from a fellow MFKer. A 13" female hystrix and a 12" male Henlai hybrid. Would the hystrix be fine with my pair now?
