its not aptasia but its taking over!!!

There is some sort of anenome taking over the tank. My peppermint shrimps are taking care of any aptasia outbreaks but they aren't touching this stuff. They get about the same size as apsasia, are brown, short tentacles, and are killing anything next to them. I have tried boiling water, calcium water mixture, and lemon juice. they all seem to kill the one im aiming for but a bunch more appear afterwards. what can i do to get rid of this stuff? here are a couple of pictures. Help!

 

Looks like a Majano. Aptasia killing solutions work decently on them.

 

Not Mojave...different breed of aptasia....very hard to kill. Mojave is a cute little brown Anemone. Cute until they take over too. You are up against a fierce foe. Good luck. After these took over mine I could not recover, and had to start over. It seemed every time I killed them, they got worse.

 

This link has the re-start process, but also has pics of Mojave, and what you have.
