they don't look like them at all. Those look like zooanthids.

you want to be sure to check around your zoanthid rocks
bec majanos can easily hide/blend in w/ them... we thought we exterminated them once only to have them growing right under our eyes in amongst the zoanthids...
luckily we caught them early enough
and got by w/ bleaching about 40# of LR (out of over 200#) and got rid of the pest once and for all (fingers crossed that is - has been over a year since finding any more!)... might seem extreme to some folks but took a chance thinking that by removing any/all rocks that were associated w/ the majanos (thus any rock that they were found on or may have spread to)... so we (perhaps) got lucky to have caught it early... i still get paranoid sometimes when looking at some of the aiptasia that show up (thinking they might be majanos)... its always a sigh of relief though !
i still shudder anytime i hear someone asking about these
only to be told by others to approach it as a 'simple' pest to be dealt with - such as aiptasia etc...

I just discovered that what I thought was nice looking coral is Majano and it is spreading. I will be trying all of the above. Another thought I have is to simply take the rock out, try and save the coral and buy new rock. I'll cook the rock that the Majano is on. this is an expensive solution.... I might try Raccoon. I know a person who put one in his tank and that took care of the problem.

good luck! would be interested in hearing how it turns out if you decide to go that route.

There must be a natural solution to every problem in a reef tank. Unfortunately, Majanos are a problem we have not yet figured out a proper solution to. There has to be something that can kill them. I think the answer lies in the stinging ability of certain corals. After all Majanos are related to corals and certainly can't be invincible. What we need is to figure out what coral can pack the most punch and physically sting the crap out of the majanos. Like a handheld bug zapper. Now I have tried this on aiptasia using an Austrailian Elegance coral and was able to incinerate them without their return. But Majanos are stronger then aiptasia. Currentty I battle them by using tweezers and stab and rip them off. Keeps them down for awhile, and isnt that much effort to take down a field of these guys when your angry. The elegance did kill some, but some survive its sting. Maybe its a matter of exposier time. I'be tried using torch coral too. Come on ppl lets figure out what can zap the crap out of them, short of a box jellyfish.:mad2: :mad2: :mad2:

I was just reading an article on majanos and the best, and most effective predator for majanos aare sea grass filefish (Acreichthys tomentosus). "They have been known to pick on xeniid corals, leather corals and large polyp stony corals, but they are usually happy to just dine on majanos, Aiptasia and foods introduced by the aquarist (Marine Fish & Reef USA pg. 10).

Get a seagrass filefish, reef safe. They will eat all manjo and aiptasia in your tank. I had one in my sps tank and he never picked on my sps. I have 3 different types of xenia growing on the back of my glass and I never seen him eat any, but I don't care about that, he hid in there at night, that's how I got him out.
After all the manjos and aiptasia was gone, he started eating some of my palys, that's when I removed him. But he also ate frozen food and pellets. He's in my buddys tank and hasn't eaten any of his zoos or palys. They only get about 3 inches long and cool as hell to watch.

I haven't read this entire thread but thought I'd share that bi-color angels eat them. I had them in 2 different tanks, an infestation to be exact, put a bi-color in both tanks and within 5-6 wks they were completely gone. They will come back if you removed the fish or if it dies. I had one die and they started coming back, added another bi-color and haven't seen one since. Only you don't want a bi-color of you have clams or open brains.

I've had a bicolor for almost a year now...totally not interested in Majanos. What worked for me was a majestic angelfish. The majestic ignored them for 6 months then all of a sudden went crazy over them! Not a single one left in my 100G. At one point I think I had close to 200 of them.
FWIW I have open brain corals and 5 clams. Neither the bicolor nor the majestic have ever bothered them. I do keep them well fed and I think that helps.

Will a bi-color angle fight with a flame angle? I want to say yes but thought I would ask if any one has both in one tank.. I have a 125 6 footer..

It depends on your fish and your aquascape and most importantly your luck.
I have a flame angel, a lemon peel angel, a golden angel, and a bicolor angel in the same 100 G tank. I have a lot of live rock and there are lots of hiding spaces/caves. I introduced all 4 at the same time. I knew I was taking a risk, but a buddy of mine had done the same with no problems so I thought I would give it a try since I was desperate for something to eat the majanos.. The lemon peel and the bi-color fought for a couple of days, but them the lemon peel established dominance and they have been peaceful tank mates since. All my angelfish seem to get along quite well.
If your flame angel is well established in your tank and /or you don't have a lot of hiding spaces in your tank then I would say that the flame angel is likely to kill the bi-color. Keep in mind that for some reason, the bi-colors are very fragile in the beginning and many do not acclimatize well to life captivity. In fact, most will die (> 80%) . Once they become established however, they are quite hardy.
If I had to do it again I would probably not buy the bi-color. I keep hearing stories about how many of these poor guys die because of our hobby.
Check out the majestic angelfish. It is quite hardy, beautiful, and did the trick for me (granted it took 6 months before it even noticed the majanos, but eventually it got the job done)
good luck!

I'm sorry I didn't read the entire thread. I have a 65 and HAD about 200 or so in my tank. Thank god I really didnt have too many corals at the time.
The best way to kill these lil guys is to get a 5 gallon bucket. fill it half way with water and get 8oz of Kalk ( I use Kent ) mix about 5 ounces or so of kalk with regular tap water. get a pc of live rock and soak it in the mixture for like a minute or so. The mojanos literally jump off the rocks and die! unfortunately most of everything will die on the rock. I have a few still in my tank that I cannot reach but they are hanging low and out of the way. sometimes they jump off the rocks and the current tanks them to the top and thats when I use a calk paste and inject them.
There is no need to burn them with a blow torch, boil or nuke the rock!
