What are these little bugs all over the glass

[Rscott]

So I recently dang near lost my whole tank
Had a bta so the classic let’s get sucked into a power head and turn myself into fish food.
I found it the same day and went to extreme measures to save everything

lost some acro from the ammonia

however tonight after all the water changes I found these little punks on the glass
They are very small and move very fast
Sorry the pics suck

I doubt it’s related

any ideas ?

Copepods which are in essence, free food for fish and coral. Wrasses and dragonet gobies eat them like candy

I was hoping you might say that it’s a coral only tank so not sure if they will
Overwhelm my tank
