Unfortunately my citron goby has taken a turn for the worst over the last few days. He has been breathing heavily and is doing an odd thing with his mouth that almost makes it feel like something is stuck in there (see video).
I have several other fish in the tank all doing fine, and nothing new has been added in over a year. I believe water quality and disease can be ruled out.
He has historically been an incredibly healthy eater of mysis and pellets, and this has happened once before maybe several weeks back and he eventually snapped out of it and started eating again, but this has been the longest Ive seen him go without eating which has been maybe 3-4 days.
My current thinking is old age or something is stuck in his mouth, I got him as an adult almost 2 years ago.
What do you guys think?
