I woke up to these little dots . They popped up seemingly over night. All that’s in the tank is one common goldfish and 8 rosey red Minnow

Look up Ostracods, or seed shrimp. I can't tell from the pic for sure.

I was thinking it might diatoms growning on the gravel

Could be that too if the brown creeps along and spreads, then likely probable. You can try some Phosguard or here is a nice chart I found it has a couple more options - phos... to remove silicates.

Update!!!

I am about 90% sure it’s diatoms it’s nearly doubled in amount and I found brown sludgy algae on my glass.
