The Pacific Blue Tang is a member of the surgeonfishes and is one of the most active swimmers of the available tangs. They will need at least a 75 gallon tank (284 liters), preferably larger, to allow for adequate swimming space. They can be fairly hardy once acclimated but will not do well in a tank that has not completed the aquarium nitrogen cycle. You will also need highly oxygenated water provided through increased surface agitation (multiple power heads) and/or the heavy use of air stones.
