GOT HIM!! I did the FW dip for about 2 minutes and he came out running. didn't see any others and the polyps are too close together to get a good look at the underside of them for eggs. I will have to keep a close eye on them for any unusual activity over the next couple of months.

SHagMan - THX a mill for the advice... in fact, thanks all to your advice.

I am looking into getting a 6-line wrasse and hopefully this will help with a more natural pesticide solution :-)

Here be the pic of the culprite I was able to catch :-) Again, thanks a million all
