Hello,
I’m wondering if anyone can explain this goby’s behavior? Every so often, he’ll gape his mouth wide open, then continue on about his day. There’s no regularity to when it happens. He’s eating and acting just fine, it’s just odd! You can see it about half way through the video. I had an orange spotted goby in another tank that did this as well, but he didn’t survive more than a week. I’ve had this guy for 3 or so months.

I’ve been chatting with Jay and taking his advice on what’s been going on in my tank, under this other thread! He has been a great deal of help! I posted these updates to that thread as well!
