Sounds like bad water quality in the 35 gallon. It could be
dead or dying snails in your substrate.
Is breaking the tank down, rinsing the gravel, washing out
the tank (perhaps with baking soda) and setting the tank up
again an option?
If not, I would suggest vaccuming the gravel in the 35 really
well. Throw away the foam or filter pads and add new ones.
