Thank you @vetteguy53081 and @Crabs McJones for helping me out, and finding out the right ID on this Critter, I really do appreciate it ! Besides the wrasses, and Flatworm Exit as @Reefahholic mentioned in the thread, is there anything else that I can do, or should do? What approach would you guy’s take? I am always very careful when I get something new and in the dipping stages, to make sure to scrutinize it well, I guess this one slipped through the cracks somehow! And just like that, when you think that everything is doing good, and the reef tank is on point, here comes from out of the blue , this tiny little monster called a Flatworm, that has made me stay up half the night tossing and turning, and forced me to get out of bed to do more research on it! I Love this hobby most of the time, lolPlanaria torva flatworm
