Do all anti-baryons eventually decay into antiprotons?

[question dude]

(high school level physics btw)

apparently all baryons eventually decay into protons, so I was just curious to know if this was also true of anti-baryons?

The lightest anti-baryon is the antiproton, so any anti-baryon will eventually decay to an antiproton.

Antiprotons are stable against decay (so far as we know), just like protons. However, sooner or later (probably sooner) an antiproton will encounter a proton and the two will annihilate:
