This is kind of strange. I have had my tank maybe 5 years and have not bought anything for it in many months livestock wise. I have never seen a bristleworm before, but today there are suddenly hundreds crawling around everywhere. Its kind of scary cause just a few weeks ago I was doing a lot of manual bubble algae removal reaching everywhere and not really looking... I did have a lot of irititation and cuts on my hand when I was done, but I figured it was the rocks and coral. Now I am terrified to be reaching around in there! Have any of you gone years with zero and then hundreds? How worried should I be about them hurting my skin?
