Beat Red Bugs, now have monti eating nudis

[Willito]

Tought luck Harvey, I had those once on my Monti but ever sinse I treated the colony, I haven't seen any for months. They do like the shaded areas and will comsume your coral to the bone. They're not fast by any means but they do multiply. How I treated the affected colony was I took the piece out the tank and placed it under running water. Be careful to submerge only the affected areas. I then used a tweezer to pick and scrape them off. I did this once for about a minute and placed it back in the tank. The damaged area was about a 1x1" and took about 1.5 month to heal. I have not seen any Nudi's since and that was over 6 months ago.

What I'm doing now is soaking the colony in some tank water and lugols for about 10 minutes or so. Then I go in with the flashlight and turkey baster and blast those guys off. I'll probably be doing this every 2 days for the next month or so.

Anyone know where I can get a couple litres of lugols?

That seems like a lot of work. How large of an area is affected? Are they all over the coral or just isolated to an area. If they are just in couple areas, try my method. I find that they don't scatter like red bugs but rather stay together in clumps. This is why manually excutting them is possible.

Hi Will,

The area affected is very very large. I noticed the problem a few days ago, but I thought it was a reaction to my interceptor dosing or something other in my tank, so the nudi's have unfortunately been left uncheck for who knows how long.

My iodine dip yesterday yeilded about 50 nudibranches

I know what you mean, they can easily be mistaken for detritus and such. If you have success with the iodine, then just keep up with that. Hope you get them all.

I've also heard yellow wrasses, can sometimes take care of them, but it's like a copperband eating aptasia, hit and miss.
