something munching my zoas

[wku5]

i have no fish in my tank and my tank is around 4 months old. I have something munching on my zoas and my yellow polyps... what might it be?

I dont know but try looking at your tank at night with a flashlight when all the lights are gone and you will be amazed at the variety of creatures living in there that you dont see when your lights are on. Maybe you will see the culprit..

May be worms....bristleworms ?

make extra careful sure it's not some sort of parasitic nudibranch. GL finding the culprit.
