After reading GoblinShark's post, I've been wondering.... :thinking:
A while back, I bought a huge rock of zoos (pick posted below). After a few months, the zoos were completely gone (see following pics). I attributed this as being poor lighting (I had 130 watts PC on my 29gallon), or bad water quality (was battling nitrates for a while).
Recently, I upgraded to a 55 gallon tank with a 400Watt MH and 2 VHO bulbs. I bought some Yellow Polyps last week, and noticed that their numbers are dwindling.
A few weeks ago, I happened to turn my bedroom light on in the middle of the night (my tank is in my bedroom), and I saw this worm about 1-1/2 feet long crawling around, which quickly crawled into a rock.
Could this worm be eating all my polyps? I've also noticed all my shrooms have disappeared as well, but not my Xenia, gorgonia, or GSP.
Any ideas?
