First corals - is this Aiptasia?

[waitwut]

New to the hobby, just added my first corals to my first tank. After placing this toadstool coral I noticed what I suspect to be Aiptasia on the rock. It looks a bit more opaque than the pictures of Aiptasia I've seen online so I'm not 100% certain.

I should have caught it earlier and scraped it before I put it in the tank but it's only been in the aquarium for under an hour - before I rip it out again and risk killing the coral, is this Aiptasia?

Can't really be sure but looks like it. Remove it anyway.

Cloud be an majano anemone

Thank you for the quick responses. I decided to be cautious and I removed it and scraped the two I could see. If they were aiptasia I have no idea if scraping them will be enough as it created quite a bit of sticky debris that was hard to get off the rock. The toadstool itself seems to be doing quite well - it was already extending its polyps - so hopefully it withstands the little bit of extra abuse!

If this was aiptasia I'm pretty disappointed that I was shipped a rock with clearly visible pests on it! Half the order arrived dead as well, this store had a good reputation but I'm not impressed after this. I will email them and ask them to help me ID it of course.

I took a photo under LED light as well, I have already scraped them but here it is anyway in case this helps with ID'ing them.

Second pic looks more like Majano and you don't want that either.

It does look more like Majano. Should I try and glue over where I scraped them off in case they regrow?

I hope you didn't scrape it in the tank. Probably sent out dozens of aiptasia/majano babies throughout the tank. You posted 2 months ago so if you didn't see any bew ones pop up then you're probably good. If you did have babies sprout up, then be more diligent next time and scrape out of the tank, superglue over them in the tank quickly or order some berghia nudibranchs from saltyunderground.

Definitely not aptasia. 2nd pic looks rfa-ish. Majano is a good guess as well.

I scraped them outside the tank. After a day or two it looked like they were growing back from the remnant in the rock that I couldn't scrape out (amazing how quickly they regenerate!) so I covered them over with a dab of epoxy.

Fortunately I haven't seen any more pop up in the tank. I'm quite confident that these weren't aiptasia - unfortunately I did later find an aiptasia polyp in my GSP that I put in the tank at the same time (can't believe this store gave me two separate pests in one order!) A peppermint shrimp took care of that immediately and I haven't seen any more of that either.
