Hi, I recently added more gravel and plants to my 10 gallon tank, and now the tank is not very visible, very small particles floating in the tank and now there are small lines swaying in the current, one side latched to the side of the tank. The things do not look like they are living. I thought it was, like, debris from the big water change(I scraped all the gravel around) but it didn't settle down after a while. What is happening?
