Hitchhikers. Spreading like crazy. Should i keep them and how would i control them ?

Those are Palythoas aka palys. Most would not consider them a hitch hiker, but I guess anything is if you did not intentionally add it to your tank.

If you want to get rid of them or just thin out the herd you could try cutting them as close to the base as you can with some scissors and then smother any remaining tissue with some epoxy. GL.

IMO if you want them gone remove the rock they are on if able. Remember palys can be extremely toxic when manipulated or damaged.

I called them hitchhikers because i got them on 2 different pieces of live rock. Didnt see them then they started popping up all over and spreading. Thanks for tge reply
