Need ID / They have taken ovver the tank!

I need an ID of these little guys that have taken over one of my tanks due to neglect on my behalf.

 

They are Majano anemones

 

Well I think it's time to do the tear-down option because they have gotten to the point of no return. I think that I will sun soak all my rock in that tank for a week or so and start over. Any suggestions will be appreciated before I do the tear down method starting next weekend!

 

Ditto. Wow, you weren't kidding when you mentioned "take over." The good thing is that the majano isn't as potent of a stinger as the Aiptasia anemone.

 

Wise choice my son. ;D

 

Yeah, get rid of them asap!! They are no good in a reef tank especially! You can soak them in hot water as well or vinegar.
Good luck!

 

wow - I have heard they were pests and could sting other coral but wow- I had no idea that they would reproduce in that quantity- wow!

 

You must have used Live Rock with all the diverse life on it . ): If you do tear it down and restart the system , thats the only way I know of to kill them off totally just start from the beginning and really soak that rock in Bleach. Toss all the sand and just start from sterile . Man these eve out do Rabbits or Lemmings And these type of animals also have population explosions when a food source is plentiful pretty muck like these Majano's and Aptasias.. Might cut down on feedings a little with the next tank. Food Diversity and and abundance is a Human factor not an animal one..Animals eat to live and not like humans that live to eat..

 

The live rock is the original rock that was purchesed in 11/2002. There have been no problems with anything in the tank until this summer when I slacked off from the hobby due to outdoor summer fun! I have the same old fish, (except for a clownfish that died last year) and corals from the 2002 purchase.

I first noticed about 10 in the tank about June. Then by Sept, I noticed that there were about 20 and now there are at least 1k.
