My suggested protocol is to use tank transfer for all new specimens to insure against cryptocaryon irritans. 12 days and two 20 gallon tanks is all it takes.

The initial receiving tank is temp and SG adjusted to the bag water( SG a few points couple of points lower than the bagwater is ok but not higher) This obviates the need for drip acclimation and prolonged stays in bag water where pH can rise and ammonia toxicity can increase once the bag is opened. This is particularly important...

t is best not to argue,
But if you do at all,
Never do so with a fool.
A fool can defeat all.

He does not care for the facts.
He does not know debate.
He’s a stranger to reason.
Logic he can negate.

In the end the fool will win,
His logic is so strong!
Decides what he does not like
And then it must be wrong!

It’s better to keep quiet
When challenged by a fool.
Else, to prove...

Tangs grow to be a spectacular reef fish; they are hardy, eat well in captivity, don’t bother sessile invertebrates, and rarely quarrels with other reef fish (except, of course, other tangs). Sounds like the perfect addition to your reef aquarium, right? The problem is that Hepatus tangs, which this poster wants to add to a small tank, grow to reach a length of one foot! They are also the fish most susceptible to cryptocaryon irritans.

Some aquarists such as ones on this thread say...
