Help getting rid of Majanos

fuseblower · 02/20/2008, 08:13 PM

I discovered what those nice little green anemones were a little too late and now they are way out of control. I have done a google search and not found any solutions to eliminating them.
I have a 100 gal reef tank and the little pests are effectively outcompeting some of my corals.
I have discarded a few pieces of LR that were covered with them.
My next move was to completely replace my LR and scrape them off of the few corals I think I can salvage.
I have heard that copperband butterflies might eat some of them.
Any suggestions would be greatly appreciated!
Thanks!

inject with lemon juice kills them quick I had about 30 of them dose the job they are now gone, its a cheap easy way

I am not fimiliar with Majanos, however I had an aptasia outbreak from rock I bought that had it, and I got "Joes Juice", which knocked it out great! I noticed that the box said it was for aptasia and majanos both. I would try it.

Also pepperment shrimp may eat it.

I agree with k9gunner, Joe's Juice got rid of my aiptasia problem and they never returned. They automatically implode/disappear when you apply it, pretty cool to see.

I agree with the others

what do you mean by you pitched the live rock. You can boil the rock and let it recyle again?

I actually have had both aptasia and majanoes and joes juice eradicated both it's been about 6 months since and haven't seen a single one. I've heard sometimes it take multiple applications to completely eradicate them though.

I went to war with my tulip anemones today. These guys are the same or similar to majanos (green with pink tips, 1" or so, breed like bunnies). I've been covering individual nems with kalk paste, which kills them nicely, but they beat me with sheer numbers.

Today, I buckled down and pulled 90% of the rocks out one by one (some I can't move, they're cemented to tank walls by coral growth). I inspected each rock carefully, and used tweezers to get under the foot of every anemone I found. Once I had pried it free and tossed it out, I put some kalk paste down where the anemone had been, to nuke any bits of flesh left over.

What I found interesting is that there were huge colonies living under and behind rocks, where I couldn't see or reach them. It seemed strange to me that with every visible anemone I killed, three would take its place; now I know where they were breeding and migrating from.

Remove badly infested rocks, deal with the nems one by one, and use lemon juice, "Jo. e's Juice" or a paste of kalk powder and hot water to poison those you can't physically remove. With paste I like to feed them some, then bury them -- kalk is very basic, it burns their tissues, so this way you're getting them inside and out. You can also try just aiming a powerhead at them, or blasting them repeatedly with a turkey baster -- whenever I turkey baste my tanks I always find little nems detaching and floating around. Before today, that is -- hopefully now the problem is under control

Good luck!

I agree but I wouldn't remove all the live rock at once if you have a heavily loaded tank with fish and inverts. One or two rocks a week in this case would be on the side of caution

HammerDude33 · 02/21/2008, 08:13 AM

i use kalk paste in a syringe and blast them in the mouth. then after they curl up and retract, put a little glob over the spot where it was. this is 100% effective.

just a suggestion for anyone else reading- try to kill them immediately as you see them to keep the massive population explosions from happening, as they happened above.
unfortunately, you won't see them under the rock, as per ACblinky's tank, but i believe for the most part you can keep them from getting a foothold with vigilance.

i've been battling Pseudocorynactis recently. basically the same situation, but on a much smaller scale. i just kalk them as i see them.

IMHO that defeats the purpose -- in my case, I needed to remove the large colonies that were hidden out of sight/reach so they'd stop producing the clones that were plaguing my tank. Taking out a few here and there would allow those remaining to replenish any that I removed. Each rock was only out of water for a minute or two, and it hasn't caused any issues whatsoever. My tank is stuffed -- several big fish, a few smaller ones, CBS, pistol shrimp, urchin, loads of zoas and shrooms, leathers -- it's very established and has a fairly high bioload. For me, kalking all of them in-tank wouldn't have been a good idea because there were just too many nems, and many I couldn't reach. Taking out most of the rockwork in a single day might be a bit drastic and not needed in every case, but for me it seems to have worked fairly well. There are a few survivors this morning, but their remaining time on this earth is short.

of cource you will be okay----I wrote the post assuming that you were going to leave the rock out longer

However, removing the base of the reef that is in contact with the substrate might cause a blip in nitrates that could be under it-

but you are on top of things--so good luck

Yes, good point about not removing all rock at once. My tank is fairly heavily stocked. However, I look at this as an opportunity to make changes in some fish that are getting more aggressive. Can't catch them w/o removing rock. So, I'll have to set up a temp smaller tank, get rid of the problem fish, treat 1/2 of rock at a time.
