So this stuff forms black trails across the rocks and glass. The trails don’t appear to move when looking at it for a brief second. But if you look at it closely, you can see that it’s actually a network of very tiny worms. If you come back a couple hours later they’ll be in a new section of the tank. Should I be worried about my soft corals or lps?
