may be Aiptasia

Hi, everyone.
I have recently set up a new tank. 29G... no big deal. Not even close to cycled yet but I found this little guy. Aiptasia anemone? It's not a huge deal now since there's nothing in the tank (except for some weird, 2" flatworm that I can't catch on camera). Suggestions?

That is definitely Aiptasia. Buy some Aiptasia-x and follow the directions, works very well. It is a big deal, even if nothing is in the tank yet, they can spread quite quickly. Don't try and pluck it out either or aggravate it, that'll cause it to release spores into the water and you'll have even more.

Thanks. I needed to make sure before I took action. I didn't even have lights set up until today...
