Lucky you. My son and husband dont get involved in my fish at all. They never help cleaning the pond or the tank. They both love to show off the moster fish. Hubby just pays for it. LOL My thought on the spines may be silly but worth a thought. I was thinking marshmellows. Or grapes. Something like that, texture wise, that wont get stuck on the spine. Foam filter blocks might get stuck. I have been stabbed a few times just cleaning. This might trigger that perfect solution for many of us who will have to move our monsters. Good luck.
