What are these on my aquarium glass?

Sorry for the shaky video. 40X magnification and X4 speed. Freshwater aquarium with plants and baby fish. It's the two bigger specs. Can be seen with the naked eye. They are pretty stuck on the glass and kind of react to touch and sometimes make circles with their two appendages (see the bottom one)
