Just got a powder brown tang for my secondary tank at around 1, temp. acclimated him for about 15 minutes and acclimated him for an hour. Once I put him in he was doing fantastic, swimming around and picking algae off of the rocks and exploring every nook and cranny of the tank. I left the lights off for a couple hours but when I turned them on, he started twitching and not moving very much so I quickly turned them on and waited another 2 hours. I turned them on again but used my blues to slowly raise the intensity incase the whites were too shocking. Once I raised my blues intensity, he started twitching again. Any suggestions on what to do?
