Pods or something more diabolical?

Hey guys just a quick question.
Monthly, I add @AlgaeBarn ecopods. A couple of months ago I used one shipment of the Galaxy pod mix.
Today while feeding my corals, I noticed in my chaeto overgrowth box these little (1/8 inch?) critters.
I've looked around at some pictures but I can't seem to find any pods that resemble what I'm seeing here.
Can anyone confirm what they may be? Sorry, it's the best photo I can get.

I’m seeing amphipods and isopods - good guys!
+1.
Amphipods have curved backs while Munnid isopods have flattened backs, though they look very similar when clinging to glass. Both "pods" are harmless scavengers/grazers that serve as live food for larger organisms.

Great info! Thank you so much!
I definitely spot what have to be Munnid. Tons of them.
So glad to know that they're not detrimental, although I have read articles that claim certain isopods (or maybe isopods?) can be parasitic to fish. Do you have any information/opinions concerning this?

No problem!
Cirolanid and Aegid isopods are the ones you have to watch out for when it comes to fish:
