I’ve seen it once but didn’t think of capturing it. It was just spitting it out and then eating it. But other then that I don’t see it happening during the day. I do see them grazing at the rocks, I’m not sure if they seeing the worms and trying to attack it.So I never see any during the day , so when people say get a predator I dont really see that as an option at least for me . I used to have a lot in another tank and a huge melanarus wouldn't touch them . Anybody have pictures of their coris or whatever wrasse eating them
