Foxface stuck to overflow

[GongShow]

When i woke up this morning my foxface was stuck to my overflow leading to the sump i freed himand he would just float around and get stuck nto one of my pumps so i moved him to my quarantine tank where he isnt looking good at all. He is floating around near the top of the water breathing fairly heavily and he is going where ever the water flow takes him the weirdest part is during the whole time he has never moved his back fin once only his to side fins. Is there anything i can do or just wait and see
