What is this?

[Guest Sachin]

Hello

My 40 Gallon has been up for over 9 months now

and I have seen these Green Anemone multiply

over the last 5 month

each month that goes by there is a new one

I have over 5 in my tank

 

Not sure if they are Pests , Harmful , or what?

The place where they are growing use to be covered by green polyp

There are only few green polyp left

 

I am looking for some advice

What are these and what should I do with them

 

Thanks

Majano- Hard to kill and will take over everthing- I have seen them actually set up shop in the middle of an GSP colony and sting thier way into territory in my Nano. Inject them with vinegar and they will be hurt but it will take many sticks to kill completely- Kalk the same way- I have had one shot success with Joe Juice. But beware, they may move on you to anew location- and you just think you killed it.

When transfering to my 90g I took each piece or rock and inspected carefully, took a small flat screwdriver and pryed each one off (dig into the coral rock). Unlike aptasia, these thing stay together. After finishing a piece, place in a seperate container and come back tommorrow, I did this for three days until I was sure none were there.

 

After having pieces infested with these, none made it over to the new tank.

 

 

From experience, I started with one years ago in a 50g (did not know what I had), by early this year I suspect several hundered and they will take over everything even growing on soft coral tissue.

Eradicate injecting vinegar or pure lemon juice; you can also use the famous juice. But you need to kill it as soon as possible or it will take over your tank.
