Repotting time for my fast growing cacti

Had to save my Sulcorebutia rauschii and Gymnocalycium mihanovichii from being squished by my now giant Mammillaria spinosissima “un pico” (phew, scientific names are hard). They were all planted in one pot, but that didn’t work very well. I’ve never seen a cactus grow that fast.
On the bright side, the Sulcorebutia and Gymnocalycium are doing great. One is growing multiple pups and the other is flowering soon.
