I’m currently raising my salinity in my 20 gallon from 29 ppt to 35 ppt just topping off with salt water 35 ppt, I’ve noticed my firefish hasn’t ate for the last two days and has been in the same spot for the last two days, but all my other fish are doing good, it was also found in the back of my lfs sump so I’m wondering if it could be old age, he is pretty big. This was him a couple days ago and I’ve attached a YouTube video of him now.

He’s also moved to this other rock crevice which is different from the video while I was typing this up.
