that looks like a nudibranch to me. do you have Zoas?

P-Dub · Feb 11, 2018

That is a nudibranch. If it were my tank I would not take a chance and remove it. However, if it is a lettuce leaf nudi I have heard they are reef safe... But I personally would remove it unless I could positively ID it and verify it is reef safe. Some nudi's release toxins.

Zoanthid eating nudibranch

I will do thanks.

remove it. check for eggs. there will be more.

I had my ZOAs on one medium sized rock and dipped them every three to 4 days and after two weeks they were all gone. You will get the big ones right away but you have to wait for the babies to hatch to get them. Coral RX did the trick for me.

Nice. Zoas are strong. Hope it works as well for you as it did for me. May take several treatments.
