It hasn't eaten for a few days which isn't out of the ordinary for a catfish, but still. I've been feeding it tilapia and shrimp. It always eats those, so it's not because it doesn't like what I've been feeding it.
I moved it into a smaller, quieter tank and it was upright this morning! Hopefully, it will come around. The streamer started to grow back, too. I hope it starts eating again soon.
