My Nasty Pest, not Apitasia, looks like a button polyp...

Did anyone guess what it was? I posted picutres already about it on the newbie forum asking, and people said it was Glass Anemones. I persisted, as it just had to much colour for glass anemones. But it was not a button polyp as it was spreading like crazy and stinging my leathers like mad, even my mushrooms were getting hurt by it.

Well I finally figured it out, while browsing this article...

It is a Majano Anemone. The ways I have heard to kill it are the same as Glass Anemones; boiling water, joe's juice, kalkwasser, lime juice.

So I am continuing my struggle against it. It seems very resiliant, if you do not inject it directly in the stem it soemtimes survives, and they shrink up fast when you touch them.

Thats right, they can be hard to get rid of sometimes, a syringe with boiling water, just get as close as you can before you see a reaction from the nem and BAM..have it......After the first syringe full, just keep forcing the boiling water into the rock in the area where it is, that has always been my route and they have never come back....

I used kalk paste when I had a majano outbreak. Well, maybe 3 in a 90g isn't an outbreak, but the kalk paste did the trick. I had only 1 pop back up several weeks later and hit it again with kalk paste. I haven't had anymore since.

Wow... that's quite a few of them... might be easier to treat some of the worst pieces of rock outside the tank to keep from shocking the system with that much Joe's Juice or kalk (like in a Rubbermaid container).

You're right -- you wouldn't want to kill everything off of the rock... I guess I should have clarified what I meant a little better. Instead of dosing all the majanos in the tank, I'd pick the rocks that are covered by them the most (and easily removed from the tank), place them in a 5g bucket or sizeable Rubbermaid with tank water, dose the majanos, give it several minutes for the Joe's Juice or kalk paste to "skin," then gently place the rocks back into the tank. Once the Joe's Juice or kalk paste skins, it dissolves pretty slowly (couple of days). The concern about dosing that many majanos in tank at once is the amount of stray, liquidy Joe's Juice or kalk paste that gets dissolved into the tank water before it skins over. That's what will alter your water chemistry. If it's not heavily disturbed, it should stay skinned over and not have such a drastic effect on your tank water. If you frequently dose your tank with a caclium or alkalinity additive, I'd suggest testing your water before dosing either additive while your working with the Joe's Juice or kalk paste to kill off the majanos -- just to keep from accidentally raising your levels too high.
