My axolotl, who use to eat with full gusto and regularly, suddenly cannot seem to open up his jaws - like he has lockjaw or something! The last thing I was able to feed him was a store bought earth worm which I hear is fine for them normally. I'm worried that he's going to die now that he can't seem to get his mouth open. I've attempted to force feed him by gently opening his mouth and using a syringe, but it was difficult and he spat most of it out. I still couldn't get his mouth open very far at all even trying to do it myself. He's definitely hungry, he comes up to the food in my fingers when I try to feed him and pushes against it like he really wants to eat it - he just can't! I feel awful. Anybody else ever have this problem?
