blue tang HELP!!

Everything went perfect last nite...i brought the fish home last nite in two seperate salt buckets i had a drip line in each and had very few drips going...i let it drip for a hour took a couple cup fulls out and let it drip again for a hour and a half...i had turned my lights off right when i got home so my fish didnt know what was going on either...i slowley started adding the fish in and they all right away sat down by the sand in the front huddle together...my two clown fish and my cardinal went to check them out and actually hung out beside them the whole night ahahah...i turned my lights on in the morning and everything was perfect all the tangs were swimming around the blue tang seemed perfectly fine...i had thawed some food the night before and added ginger extract to it so it could absorb all night...i fed them at 12 and they all ate the food...so everything seems it worked out fine....thanx everybody for the help appreciate it !!
