worm

So I have a few bristle worms in my tank.. however in this video it seems that it has a green or greenish blue shimmer to the top of it. Is this just from the lights or the shimmer of the water? Just curious if anyone knows?

I have started to see a number of these very small (1 - 2 millimeter) brown/orange worms on the zoa garden. Zoas seem fine. I collected one and put it in water on the top of a small plastic coffee lid. Photo and video below. I've read there are benign worms that match this size, but I'd like...

Hello, I recently started noticing 2 small white centipede like “bugs” on the glass of my tank. They have antennaes, many “feet” like a centipede, move slowly, and are completely white. The bugs are very small but still bigger than pods. My tank has been fallow for 8 weeks now following a...

Have had these in my tank for a little while now and haven't been able to figure out what they are for sure. They're white and black stripped and like to collect around this coral and I'm not sure if they're benign or something I should be removing. Here's an image, please ignore the turf algae...
