So I recently bought a figure-eight and leopard puffer and need to start a pond snail tank. I had an empty 10 gal and my LFS gave me 5 snails to start it up. I saw no progress for 8 days until I saw these little blobs with black specks that look like jelly. Then I took notice to the specks on the glass. They were moving... Four walls and ground are covered with tiny specs... Full on outbreak on my hand.
