pest anemone

Hello all found this little guy behind one of my rocks. It’s tiny and in a very low light area. On first glance I thought it may be aptasia, so I went to get it off the rock. It closed very quickly after being touched. After thinking about what I saw I wasn’t sure it was actually aptasia. I’ve...

I had an aptasia in my rock and I used F-Aptasia to get rid of. Then I noticed this right next to it. It’s wavey, could be from the flow but i am not sure. What is it? My tank is about 9 months old.

Found one on rock found one on a dying coral. They are fairly small with the larger one being a little over 1cm maybe.

Hey everyone, saw this land on the sand, I have some rock flower babies so thought it was that grabbed it out and put it in a cup. Couple days later opened up not so much. Is it a Majano? Something different? It’s a nice red lol. I did a google/ forum search missed anything that looked to...

Found this guy in my nano tank. Is it an aiptasia or some other type of pest anemone? Will berghias eat it? The polyp is about the size of a dime and the markings are a brighter white in person. Thanks everyone for the help.

Hello, Are these ball Anenomes? They are all over my reef tank and seem to be bothering my corals and stay open all day. They also attacked a baby hermit, and seem to be really aggressive. Also, any natural predators? (For a 40G tank) Or other alternatives to remove? Thanks in advance!

Hi, all, Several months ago, I set up an experiment to deal with elevated nutrients in DT, added an HOB filled with chaeto and a light. The experiment doesn’t seem to have worked; phosphates still ungodly high but stable and as a bonus, I found the algae had been home to aiptasia (yay). I...

I just dipped some new frags and found this Anemone in with them. It doesn't look like any Aiptasia I have ever seen, I'm unfortunately really good at getting them in my tank... But this is definitely some kind of Anemone. Thanks for the help in advance! lol.

Hi guys, Recently started my first saltwater tank, and having difficulty identifying what pest this is. I assumed aptasia but looks different from the aptasia pictures I see online, it’s thinner and has small balls/heads at the end of each little thread… I introduced some Berghia nudibranches...

Hey all! Relatively new to the hobby with less than a year of experience. Noticed my lepto wasn’t looking too hot and shortly after, I noticed these guys hanging out on the underside of the frag. My searches through the forums lead me to believe they’re hydroids, but I was hoping someone with a...

Hey everyone My tank is coming up to 4 weeks old now and these rogue anemones have popped up! The guy in the lfs said they are ball anemones and to remove them with tweezers but I’m scared they’ll multiply and cause more issues! I wasn’t worried about them but I plan on adding sexy shrimp and...
