I was hoping this wasn’t possible. Hopefully he comes around for you. Did you raise him or buy him as an adult like me?I had this same exact thing happen with my male jag. One night I approached his tank and spooked him, he pin balled around the tank smacking the glass hard. It’s been 3-4 months since this has happened and he’s still the most skittish fish I have. Hardly eats and the only time I see any “normal” behavior from him is when he breeds. I’ve tried covering the top of the tank with duckweed, hides, dithers, different tanks and he still hasn’t came around. He even makes the female skittish who normally isn’t.
