Is this a female?

This one has been hanging around the alpha’s cave for almost a week now. It’s quite active during the day even when I am directly in front of the tank. The general body shape makes me think female but I’m not certain. From the bottom and top view in the video, can someone back me up or disagree?

Also, it is not at all red in person; I’m not sure why it looks that way on camera (my red shirt 🤷‍♂️)
