By the way... Those are not red-ears! Those are Ornate Sliders Trachemys ornata They are native to the western coast of Mexico from the areas around Alcapulco to Mazatlan and even a little further north. They are great turtles, but you will normally find them a bit more aggressive than even red-ears!

Thank you my first reaction was to try and separate them. They eventually stopped after I let them be @Markw84
Yes you know your turtles mark
I have two females a Belize and a Nicaraguan ornate the male is the Mexican.
The Belize is the biggest and the most outgoing the Nicaraguan is growing rather slow
