I'd say good chance of any Halichoeres wrasse eating flatworms and while there is certainly a chance of any of your wrasses not liking his introduction you are definitely adding in the right order. The yellow coris imo is the most aggressive of the bunch you named so better chance adding him last. My guess is there will be some aggression but the coris should be able to hold his own in that group. But nothing is certain of course.Quick couple questions for the experts. My current wrasse stock is a Potter’s,Black leopard,jeweled wrasse and a Moyers in QT to be added later. My dilemma is I have a flatworm issue and was looking to add a yellow coris wrasse, while calling to look around none of the lfs locally have them but one told me that the yellow and black leopard may not get along and that they’ve had success with blue stars eating flatworms. I understand no wrasse is guaranteed to eat anything but generally is there any truth to either statement? Thanks
