You know BigCT I have wondered many many times about that 10gal per inch rule and found nothing to support it. (not that I'm disagreeing, just couldn't find out why).
I've had 3 RES' in a 20gal long tank for nearly a year.. they started as hatchlings and are now all around 3" or a bit more.. no problems with dominance.. and they "seem" to be happy.. swimming all over etc. but its obvious they can use more space. Not to mention its a pain to keep the tank clean. 3 turtles in that little of water.. makes one heck of a mess haha.
