My bettas keep burying themselves and that kills them because they can't get oxygen. Why are they doing that?

It's possible that your bettas are trying to hide or build a comfortable sleeping place in the substrate. If you don't already have plants and other hiding places in your tank, try adding some. If the problem continues, try removing the sand or gravel--bettas can thrive in a tank with a bare bottom. Check to make sure there isn't too much light shining into your tank, since this can bother bettas and encourage hiding behaviors.
