it's interesting how lungs will react to cleanings/intrusion by the fishkeeper into the tank. my big congicus has gotten meaner as he's gotten older, but once he realizes it's a whole arm in there (not just fingers) he tends to back off.
still, a good practice (as you are already doing) is to keep one eye on what you are doing in the tank, and the other eye on the lungfish at all times!--
