I doubt I have an “infestation”, my tank is pretty new, and I picked up 3 montis at the recent frag swap. 2 are just encrusting the top of the plug, one was very well encrusted, with crevices coming off the sides of the plug. This one had some dead tissue, and I think was patient zero. I was just surprised I didnt see anymore come off after the dip, I thought I would see some. Only one bristle worm crawled out, and I was really blasting all of the crevices with my pipette. I think it was just one of those one in a million chances I saw it on the glass rather than a high density leading it to be on the glass.Definitely looks like it. Seems very common in frags, including from the club (maybe particularly from since that's where I've gotten them from).
Check all your montis for lines and white spots and be very aggressive about scraping or tossing pieces. If you see one climbing on the glass, you almost certainly have an infestation.
Also if your tank is big enough, they can serve as wrasse food, helping keep it under control.
I’ve got a leopard, they can’t single-handedly wipeout a pod population. If your tank has a healthy ecosystem and you’re not starving the wrasse, pods will be reproducing in numbers it (and other predatory fish) can’t wipe out, though I think it’s a good idea to supplement with fresh pods occasionally.Also, I do like the look of some wrasses, namely leopard wrasses, but I think I’m gonna pass on this tank. I’ve heard that they can wipe out pods, and I want to build a pod population for a mandarin
