Something Infestation

[finsurgeon]

Neither of my spotted mandarins, nor my green mandarin or red scooter blenny ever bothered to look at my flatworms. Nor did an arrow crab. Blue velvet nudibranchs went right after them, even eating one I put into the bag while acclimating, but disappeared into the rockwork to melt the first day on both occasions I acquired some.

Finsurgeon, that is most terrible

my cleaner wresse ate mine

My sixline cleared them from my tank, though I didn't have a horrible infestation. Still have them in my refugium but the display is clean.

I'd suggest flatworm exit and getting a wrasse that is known to prey upon them. Should knock the numbers down far enough that the fish can keep them under control.
