Hello, try researching Reeve's turtles (Chinemys reevesii), the stay small, are very personable and typically communial. I have an adult male that lives with my 3 emydura subglobosa and there are never any problems. The Pink belly side necks (emydura subglobosa) are also very cool but get bigger than a Reeve's turtle. I can't speak to any of the other types of turtles that stay smaller since I have not kept them but I am sure someoen else will chime in.
