So I recently created a thread about getting a mandarin. He has been fat and healthy and eating frozen but to my dismay the lights went out because of my timer. We were hanging out in the basement when all the sudden he goes nuts, attacking the glass and shoving his head in the sand. I am worried because he even banged his head on the rocks. I turned the lights back on and instantly he resumed swimming like normal and looking for pods. Should I be worried or did he just go nuts because the light outside of the tank.
