Larger Pods All over Zoas At Night?

[joro]

We're currently about halfway through a fallow period - we had a bad outbreak of ich/velvet that killed off our fish inhabitants - and we've noticed at night some larger pods all over one of our patches of Zoas which are in the sand currently. We've always had a pretty decent population of pods via our refugium but the number and size is a little concerning, so I figured I would ask. I couldn't get a good picture of them but I would say they are between 1-2mm in size, browner in color than our normal - much smaller - pods we see on the glass and in the fuge. The zoa colony opens during the day without issue but not sure if this is something I should be concerned with?

Get a 6 Line Wrasse.

I Keep one in every tank I have because they are awesome at eating pests.

So I was able to get a few "decent" pics tonight and it appears as if they aren't just on the Zoas but literally everything in the tank. One variety is completely translucent (pictured in #1) and the others seem to be brownish/red through the center (pictured in #2 and #3). Any idea on what these may be?

They are amphipods.

Their difference in color could be because they are a different species. More likely however, it's because of the difference of what they ate.

From what I can tell from the pics. I second that they are amphipods . They are harmless and fish eat them . They also eat waste , uneaten food etc.
