Tiny white critters on glass
I returned from vacation to find little white critters on the glass of a 5 gallon aquarium. They are perhaps the size of a pin head and are white to off-white. They are round, but the body narrows a bit as it comes to a very tiny head. I know they are critters because you can watch them move and stop, move and stop. Anyone know what they little things are and how freaked out I should be?
