Well. I do gravel vacs when I do my weekly water changes.. I admit to overfeeding a little bit. Or a little more than a little bit.. okay.. maybe way too much.. I guess it's kinda like the only interaction you get, and I want to feed them.. and my kids do, too.. then hubby gets home and HE wants to feed them.. but I guess that'll have to stop.. and quickly!! I think I won't feed them at all tomorrow, and do PWCs for a few days and see what happens. The fish all seem ok.. swimming fine.. no signs of stress.. thanks for your help, guys.
