What are these?

[Reefing Reefer]

I have a Fluval Evo 13.5 that's been running for the past year, today I noticed these little guys all over my glass. I'm not sure what to make of them, I'm assuming they are some sort of a pest. I initially thought copepods, but I haven't introduced any to my tank - maybe they came in as hitch-hikers? Any idea or suggestions on what to do about them?

Thanks,

They are pods and make it in our tanks on frags, rock etc. nothing to worry about

Follow up question, would these guys be a sufficient food source for a mandarin goby? Thanks for the response, much appreciated.

Yea that is what they eat but a mandarin would quickly decimate all the pods in a 13 gallon tank.
