I have these beetles in my tank...

[CritterKeeper21]

So I have probably about a dozen of these super tiny beetles in my tank. They are so small that the only picture I could get is super blurry. This is the best picture I could get. They smell musty when disturbed and they find their way into my house fairly often. They seem like they eat just about everything, but they don't attack my scorpions. Any ideas about what this could be? I have more pictures but they are not great.

Hard to see by the picture. Have you fed it mealworms or other worms that pupate?

No, these are wild beetles that I caught.

Some sort of darkling beetle. They won't harm your scorps.

Most likely a Blapstinus species. Cute little Tenebrionids, pretty easy to care for as well.
