[reef.geek]

Hi everyone, i just spotted a detritus worm in my tank,i change 10/20% of ky water every week and i do a big water change once a month. This is the first time i have ever seen a worm in my tank and am not sure what to do about it or if i should be concerned? Any tips ?
Thanks in advance

Depends on what kind of worm it is. If it's a bristleworm or dorvilleidae worm they're harmless. If it's a fireworm or bobbit Worm they're harmful. Can you grab a pic of the worm in question?
