They are actually really small in comparison to other nudibranch's i've seen. 2-3mm in length, which i why i've never rally noticed them.

Going to try an nuke them and any eggs with a iodine dip. May even have to resort to a copper dip, if they come back.

You MUST do something about them now, if you want to have any chance of keeping your monti's.

Regular Iodine dips. I've even done two copper dips. The recession has stoped, but they have almost killed both my big green monti cap, as well as the danae.

I doubt that i have killed them, i'm sure they'll be back. These things are nasty!

Next to impossible. I've had them for a while, manual removal is an option I'm trying but lost my Monti cap, green engrusting, and trying very hard to save my orange cap at present.

the best option is to remove all montis (every last bit) and leave them out of your tank for 6 months at least. this way the little beasties die off, and there eggs hatch and die etc and you can start fresh. I should have done this myself but my little orange cup monti is so nice.

I thought I had them beat but had to siphon another 6 or so off it last night after not finding any for almost a month.

i have them on a monti about 6-7 months ago, they started eating it from the middle - i noticed a white patch in the centre of it, which kept getting bigger - they were all underneath it. i just removed the monti altogether [its still outside on the porch]. i have just added another one, hopefully there are none left in the tank.

Still got them. I just end up taking all my monti's out of the tank every month or so, and check them underneath and blast any eggs and nudi's with saltwater to get rid of them, and keep their numbers down.

They always seem to come back. I've tried freshwater dips (which monti's REALLY don't like), light copper dips, iodine dips.

The monthly removal seems to keep them from totally over running and killing the corals they are on however.

Lucky most monti's grow so quickly.

Thanks Drifty ( Where's Layton when I need him ! :lol: :lol: )

Whatever I've got can't be it then, nowhere near that big.

Two of my montipora have developed some pale patches over the last few months & I've been worried about this, and sometimes have been able to see some little tiny white things in the area, too small to make out properly.

Perhaps I'm paranoid & they're just a bit of detritus.

Graduating, dining, and drinking :D

The biggest ones I ever saw were 2 to 3mm long, the eggs are much smaller, so I guess they could range in size from that of the egg up to a least 3mm
