So... I wondered the same thing. It's my only smooth skinned acro and the last one I added to the tank ~ December '15.
I always take pictures with the UV off, and you see how pink and smooth they look pink-on-pink. This time, I used the UV to show how it glows and noticed them.
I took a video to confirm and yes, I think they're red bugs. I'm surprised because I didn't think coral can grow with red bugs on it. I'll post the video in another thread since I want this one focused on coral ID. I'm amazed how UV makes them pop up so clearly.
I took it out immediately and dipped it in Bayer. None visible in QT. since it's the only smoothed skinned acro, I think the rest are safe, but I'll be checking them.
