Please help Reef Central. i have a 220g F/O with no live rocks. there have been no new additions to my tank except for a Scribbled Angel last month (who went through a QT with no problems). I have no live rock. A few moments ago I noticed on the glass that there are thousands of very tiny wormlike creatures attached to the glass. They are moving around, some quite quickly, and some are up to 1/16" big. My fish (angels and tangs) are spotless and otherwise fine. I have heard a litlle about flukes; could this be? I am appealing to Reef Central experts only please as I need to do something and I have no clue on where to start. I have a 25watt UV that obviously is useless here. I would post pictures but these critters are just too small.
