Hi , im in need of help, my Niger triggerfish has been inside a hole in live rock for more then a week and has not eaten anything for more then a week he came out of his hole this morning with both eyes bulging out his eyes arent grey but have their normal coloration but he is blind to both eyes so I went to a local fish store and bought penacillin antibiotic tablets i put him into a isolation tank and put the dosage needed , he is moving around but cannot see and is very hungry, is their a chance he will regain his eyesight with treatment in a few days or is their no chance , thank you
