I recently moved the rock with my mushrooms. It used to be on th sand but now the bottom is exposed and these sweepers come out. Randomly throughout the day it spits out what looks like a loogie that dissipates in the water. What is it? Good or bad? Nothing seems agitated by it!View attachment 23189View attachment 23190View attachment 23191View attachment 23189View attachment 23190View attachment 23191
