I have 2 (painted turtles/red eared sliders)turtles, one male and one female. Well, they keep doing this weird thing where they stick thier front legs out and kinda... shake or vibrate them at each other. What are they doing?

Put on some Barry White lol
hes saying to her "Lets get it on"

That is mating behavior. If your tank were much larger -- as big as a pond, you'd see the male swim in front of the female and then turn to face her. He swims backwards as she continues to swim forwards.

He then uses his front feet to send little currents of water onto her sensitive face and neck, and if things go well, he will eventually move up to actually stroking her face and neck lightly with his claws.

The female may shake her paws at him for the same reason, but generally he starts it and does most of the caressing, and he does ALL of the swimming-backward part.

It's very romantic when you see them "dancing" this way prior to mating in a larger body of water than a tank. Very graceful. :)

Painted turtles do have a similar sounding mating ritual. They face one another and the male shakes (or dances they call it) while attempting to stroke the female with his long claws.

My painted turtle is only with fish but he still jumps in the water and does it to his own reflection!

OK i have a question....

my turtle does that same thing with his legs right , but like he does it when i put my fingure up to the tank... do you know why he is doing that ??

please help , lol :)

ill upload a video so you can see , and maybe you can help me out , cause i'm only 15 and don't know that much about them . kk

IT could very possibly be a mating ritual.

Any chance that you can capture that on video and post that?
