So Ive had over a 20 year run keeping snails out of my tanks. It ended 5 or 6 weeks back when I used some watered down bleach (unbeknownst to me) after buying some plants. So, for the past few weeks Ive been busy killing snails in 3 of my tanks. Yesterday I walked by our Amazon tank and while inspecting the glass closely I found these little TINY white "worm" looking things scurrying across the glass. These are TINY! Like the size of a hair, maybe a 32nd of an inch long at the most. If youre not looking closely, you will NOT see them. No idea what they are. Baby snails of the bigger one? Which brings me to the bigger one. While inspecting the glass this huge guy comes flying by. Ive never seen a snail move across the glass like this guy. His shell is almost the size of a penny and its translucent. Any ideas what either might be?
