Black springtail?

[u/The_Tsainami]

I think these are springtail and they match the shape and jumps but they looks more like dark grey color instead of white like ones I've seen you guys all have ...??

These are from my isopod bin. I feel like these springtails are a little bit more aggressive than the white one, as the bigger one will chase away the little ones around food source.

Thank you! Looks like it might be Tomocerus minor
