Hey all! I was looking at my tank and found this little guy milling about on the glass… I’ve seen some little guys like this when i had my big tank up and running, everyone seemed to be fine. (Everything is extending and happy so not sure if I’m over reacting)
but now I’ve downgraded to a small nano with a few pricey showpieces and would have to have any sps/Lps flatworms. According to this little common reef pest it might be a rust worm?
last picture is one of the tank from 2 minutes ago, everyone fully extended and happy! So maybe not harmful???
If anyone has any other possible id /maybe a natural predator like a spotted mandarin?
