Bristle Worm MIA


About a year or so ago I found a large bristle worm had come into my main tank when I added a large piece of live rock. He was about 10" long and about as thick as a pinky. I was told that he was harmless and would feed on detritus, so I never tried to remove him. I used to see him every 1-2 weeks, but I have not seen him in about 3 months. Is he dead? I have not seen any spikes in Ammonia or Nitrite, but the Nitrate level has been a little higher than normal for a while, so I have been doing larger water changes. I think I know where he hid out under a large rock. I think I should do nothing but isthere any reason I should try to find him?

If your numbers are in the safe range there no concern. Just keep tabs on it, it could move up fast depending on the size of the decomp.
