What are these plant/Anemone looking things

[jbassking]

These things started growing in the tank recently. They started on a single rock but have been spreading now.

What are they?

 

[Lionfish Lair]

Looks like aiptasia.

 

[jbassking]

I hear those are not good for the fish

 

[ciscomania]

aiptasia is one of the worst pest to have. I would try to get rid of them ASAP before it spreads

 

[Higher Thinking]

Just use some Aiptasia-X. You'll be good. Or Google some homemade remedies. Definitely kill them though...

What's the best way to get rid of them?

Yeah, those things are insane! I started my tank with dry rock and sand and made sure to not let any water any fish or frag came in into my tank, and even pick off every coral off of the base they came on and guess what? Yup, you guessed it, I still ended up with aiptasia in my tank.

Peppermint shrimp, berghia nudibranch, filefish.

Thanks everyone. I'll get some stuff first thing in the morning.

Make a "paste" with kalkwasser. I fill a shot glass 1/2 full of the kalkwasser and the rest with hot water and stir it up. Turn off all flow. Use a turkey baster or better yet a syringe like you can get from a veterinarian for medicating liquids to cats. Shoot the paste onto the aiptasia until you bury it. Leave the flow off for a while to make sure it stays down on it.

Don't mess around with all that... Take the whole rock out and throw it away. Seriously.

I've used both lemon juice with a syringe as well as Aptasia X. Both worked for me.

In my personal experience, true peppermint shrimp will do the job, but...........

If you have or will have LPS such as frogspawn, torches, etc....be aware that they can and do attack them to the point of completely removing all tissue. It's hit or miss, but when they go rogue, it's quick and devastating. I have witnessed this first hand years ago and have read countless stories on multiple forums of this happening. It's real.

Now, I have use kalk paste, lemon juice and even still have a diy majano wand that I built, all work, some better than others. You must get all the tissue. Otherwise they spread like wild fire.

I have heard this before, I've never had a problem yet.

They really don't bother fish and some fish will eat them. They are bad because they are highly invasive and will sting your other corals.

That's a little overkill, you think..

 

[cnseekatz]

Nope... I don't. Every other method, and I mean EVERY other method is hit or miss. If it's just one or two rocks, and it's not too big a disruption to the tank... remove them entirely. Other methods can work, but are not guaranteed, and could just as easily cause a massive outbreak. I've been there.

The peppermint shrimp have worked well for me, but they also stripped all of my acans down to the skeletons in less than a week. Don't bother with a filefish, they're 50/50 at best. Berghias do an amazing job, but they take time, and if you have any wrasses, they'll be eaten before they can be effective.

Nip it in the bud before it becomes a serious infestation.

One thing to be aware of is that whatever method you use, if the aiptasia feels threatened, it will eject many teeny larvae into the water and even if you get rid of that one, the larvae will cause another outbreak down the line. Aiptasia is truly a menace. P.S. Welcome to R2R.
