Little white crawlers

[MisterMonopoly]

Hi all,

What are these tiny white things crawling on my glass? They also seem to prefer to hide in darkness.
Can they cause damage to my fish?

Hard to tell from pic, but they're most likely isopods

Took me 5 minutes to get that pic. They are tiny and my camera kept focusing on the back.
What are isopods?

One of the many type of pods found in the reef tank. Amphipods,copepods,isopods...

I was able to expand photo. Pods. Pods will provide a surge of food energy to varied filter-feeding invertebrates (e.g. corals) and microcrustacean-eating fishes such as mandarin fish and seahorses
