Last night I did my weekly check on my tank just to make sure everything is running smoothing and I saw what I prey aren't black bugs on my setosa. I don't know how I would've gotten them, I haven't added coral for months and this setosa frag is well over 6 months old. I didn't notice these things on any other corals and they were on my other setosa frag or montiporas. Any clue what these could be? Sorry for the horrible picture, it was the best I could do.
