so update, took him to the aquarius where someone told me a professional could take a look at him. ill just say he got his mouth open and said his teeth were fine. didnt really help much but i hope hes right and if so i can cross that off the list. upon placing him back in his hospital tank, i noticed his mouth was opening and closing a little (almost normal id say) more than b4 i took him to the guy. so im wondering if his mouth was in fact locked bc of his tooth? or misaligned? idk yet as i wont b able to try to get him to eat till he's destressed (proly tomorrow) if not, i am in need of a way to get his mouth open?????? the "professional" ended up using his knife (didnt hurt him) but theres no way in hell i would every do that to my lil guy... open to any suggestions on how to get his mouth open without hurting him.... def needs to b small, even a popsicle stick was too large.
