The male swims towards the female and starts caressing her face with his long front claws.

He might also swim around her in circles. He might also strike her front shell lightly with his claws (this looks as if his front legs are trembling).

If she is receptive, she will accept him, otherwise, a fight might start.

The mating itself takes about 15 minutes.
If after 45 minutes, the female is not receptive to the male's dance, you should remove her from the tank and try again in about two days.

We got a new turtle for a playmate for our male turtle and naturally we picked a female one. The moment we placed her in the new 80 gallon tank that we got, our Turtle started acting weird around her so I had to check the internet to know what is going on. The captions above are the information I was able to gather.
These pictures are taken on the day she arrived, July 12, 2005. We just call them now Turtle and Mrs.Turtle.
Currently we are preparing a small tank where she could possible lay her eggs.
These turtle specie is called the Red Ear Slider or RES.
