These just showed up in my nano reef or at least it's the first time I noticed them. They appear to be a tiny hard tubed feather duster that withdraw quickly if I hit them with a burst of light. The tubes are very small 1/4 inch at most, and the tops are red in color. My large peppermint shrimp took out my soft tubed feather duster, but seems to be ignoring these so far
