Flashing in Africans

Hi guys, Ive noticed in the last few weeks a lot of gill flashing in my malawi tank. Anyone have any ideas what it could be? Not sure if gill flukes affect africans. Regardless of what it is, it seems to be really upsetting them as it looks very irritating for some of them. What am i meant to dose with? Ive dosed a couple of weeks ago with Big-L wormer hoping it was some sort of parasite but that hasnt really helped. Help much appreciated, thanks!!
