I have a roughly 3 year old red eared slider that I rescued from a neighbor who had no idea of how to care for him, he has since recovered well. Last year I moved him into a 29 gallon aquarium and he nearly doubled in size since! Obviously I have to get him into a larger tank. There is a pretty good chance that I will be inheriting a 55 gal and want to know if that would be adequite for him. Thanks, Russ.
