updates??? did the coris wrasse or emerald crabs take em out?? yes these things suck!! ive tried snapping them off, plugging w super glue, covering holes w epoxy where i couldnt get to them w glue, cutting WAY back on feedings and have more now than when they first started cropping up. I think I will try the emerald crabs if that doesnt work coris wrasse, last resort ro bath and manually removing and if that fails im pulling those rocks out and burning them lol
