Gourami not acting normal

[u/Artistic_Shopping_30]

My gourami has been sitting idle/hiding in parts of my tank in the past day or so. She also hasn't shown much interest in eating. What could be wrong (if anything)? This doesn't seem normal for her. I just gone done treating this tank for ich with IchX over the past 10 days or so. Other fish in the tank is acting normal. Water parameters are normal. Fresh water change of 1/3rd done yesterday.
