I have to agree with way2fst4u's earlier post. I'll probably take flak for it, but I think the 1 inch to 10 gallons ratio is too simplistic. For one, it uses a measure of length to determine volume, which can only have limited accuracy. Using the 10:1 guideline, an 8-inch adult gets the same tank, 80 gallons, as two 4-inchers, or two 3's and a 2, or eight babies--when there is a world of difference in mass between those combinations. Second, it forgets that the turtle roommates don't draw a line down the middle of their tank and split it 50/50, they share the space. So, effectively, each 4-incher in the above example gets 80 gallons of living space. Great for them, but probably more than needed. When two humans share a 500 square foot apartment, they would never say they lived in 250 square feet, because most of the living area is shared, with one private bedroom for each occupant. Likewise, turtle roomies should be able to hide from one another, of course, but can share swimming space, no problem, so long as they aren't aggressive (in which case they shouldn't share a tank at all).
To keep from rambling, and to keep it simple, I'd say a better (but still by no means perfect) guideline would be 10 gallons per inch for the biggest turtle and 5 gallons per inch thereafter. Kind of like a buy one get one half off sale. So the two four inchers would get 40 + 20 = 60 gallons, or the 8 babies would get 10 + 35 = 45 gallons. And, as above, the bumbling 8-inch monster would get the 80 gallons he needs.
Is it great to give them as much room as possible? Absolutely--I'd love to give ours a whole room. But I think, as a minimum, the 10:1 ratio is too high when it comes to multiple turts. Just my humble opinion!
