I have had a queen angel for about three weeks now. He was reluctantly eating food but recently stopped. The last few days he was snapping at the food but appeared to be missing it. Today he was trying to eat and his mouth wasnt moving, he was motioning to the food like he wanted to eat it but it just was bouncing off his lips. Did a search for lockjaw and only found info on puffers and lionfish. Any help would be appreciated.
