Hey,
I was re-aquascaping my Bf's and my tank (honestly not sure what the proper English is for that). When I flipped over one rock I came across these fuzzy things moving across the rock. What are they? Are they harmful? If so, what do I do to get rid of them? I can't say I've ever seen anything like them and my boyfriend would be likely to know, but unfortunately he is overseas and it is 4am for him right now.
Thank you in advance for any help at all!
