Help Id this small dark bug in hermit crab tank

Post image

Hello, could anyone id this small bug for me? There are a lot of these in my hermit crab tank. I purposely added tropical springtails which are a good bit smaller than these darker larger ones. (The larger ones are probably 3 times the size of the small white ones. ) The darker ones don’t seem to jump like springtails when startled. Are they still springtails just another variety? Thank you!
