mirror

I bought two firefish (mistake). The smaller of the two has been nipping at the larger who doesn't seem to make any effort to move away. I've read that they don't fight if put in the tank at the same time (which I did). I've also read never to keep two together unless they are a M/F pair...

Hey my fellow reefers. I had a question. My fish keep seeing the side glass as a mirror reflection and keep attacking it. I tried to put a piece of wood outside the glass to block the reflection and nothing.. I tried an all black panel with the same results. I don't want my fish to stress out...
