Hey guys just curious if anyone knows what this is that I found on my ultra polyps slugging around?

Looks like a nudibranch of some sort, probably not what you want on your corals. @ISpeakForTheSeas @EeyoreIsMySpiritAnimal seen this one?

@JoJosReef i think your probably right I just googled nudibranch and the two antennas that it had were identical although body style was a little different… looks like they come in different colors, shapes and sizes.

Welcome to Reef2Reef!

Yeah, that looks like it’s probably a nudibranch, but for ID purposes, a top-down shot and a straight-on side shot both showing the nudibranch’s full body (extended normally like in a bowl of tank water) would be useful.

That said, based on what I can see in the pics above, I’d guess it’s an Arminid (taxonomic family Arminidae) species of nudibranch, so it most likely eats octocorals (soft corals, gorgonians, GSP, etc.). So, as @JoJosReef said, it’s probably not one you want in your tank.

I’d keep an eye out and check any octocorals in your tank to see if there are any more nudibranchs or nudibranch eggs on them, and remove any you find.

thanks so much for that info! And I will definitely keep an eye out for more and eggs as well. I really appreciate you guys!
