I have a white cheek tang and a gold striped maroon clown that have been in my Q tank for a week now. They were in work for a week before that and are both eating like pigs and appear very healthy. I"m going away for a few days and don't trust the water quality in the Q tank. How much am I risking by adding them to my display tank now? BTW, there is only a blue devil damsel in the display due to a problem a month or so back.
