Treble, alto, and bass clefs?! Bro I can barely handle bass (I’m mainly a ukulele and guitar player). I also play mallet instruments (xylophone, marimba, vibraphone and glockenspiel), so on the rare occasions I do have music with bass clef (pretty much just for marimba) I cannot sightread. I can’t read alto (nor tenor) clefs at all though. Good luck with that music.
