so my beardie is 2 years old now and i had recently fed him bsfl. he would twitch away from his food when he didn’t want anymore so I stopped feeding him. i put him back in his enclosure and offered him mustard greens (which i do everyday with some fruit dusted in multivitamin and calcium) i went to go check on him like 20 minutes later n i saw he had a black beard which he never does. he’s actually been gaping at me since like two days ago. so anyway he’s shedding so i just brushed of the black beard as him shedding. i come back like 5 mins later to see he threw up his bsfl. his throw up had some green and red stuff is that mucus and blood?? it looks solid and i feed him greens and tomatoes quite often since it’s his favorite. what’s going on?
