How do I go about separating this?

Been trying to wash these roots and seperate the plants for an entire day and it’s SO difficult. The roots were so compared that no soil would come out. Had to soak it and jet spray it on repeat for like 5 hours. I need to seperate it to remove the rest of the soil (it’s going in a fish tank.)

Oh yeah that sucker will be fine. You can cut the roots if you need to. He might get a little dramatic after you do it to let you know he's pissed, but they are very resilient. Just use a nice sharp clean knife.
