general rule of thumb is 10 gallons per 1 inch of shell so you could probably get away with a 75 but a 90 would be ideal
A 75g and a 90g both have a footprint of 48x18" so how would the 90g be better?

For the record... 8 inches is NOT almost full size...that's about half full size.... red ear sliders are some of the largest water turtles that are commonly available and routinely reach a shell diameter of 18 inches or more... It does take some time but they do get there. I wouldn't even bother with a glass tank for them, as someone else mentioned... checkout water land tubs....
If you take it out to let him roam the room for exercise I dont see a problem. I kept 2 painted turtles as a kid in a clear tote container with rocks water and sand, painted turtles get bigger than red ears, but mine also got to play in the backyard everyday, they always seemed happy to me and lived a long healthy life. For turtles I think a good diet proper heat and exercise are key. There not as lazy as some people think, just slow moving lol
