5" is not a fully grown purple tang.

About 10 years ago I tried a purple tang in a 4 foot long 75, worked okay for about 6 months and then it started to grow. Around the 4 inch mark it became very aggressive -- to the point of drawing blood on a male A. clarkii.
There is no way I would attempt one in a 4 foot tank again, let alone a 3 foot one.

It appears that you have already made up your mind on this, so good luck. As for that article, I strongly question a lot of things that he says and does, so I, personally, don't put any stock into it.
 
The ratio thing is silly. That's a tank with no rock. Are running BB or rock less? If you are going reef most people fill over 1/3 of the space with rock. Actual swimming space is will be very restricted in a reef tank

This sounds like a case of "can vs. should". Can you put the tank in there? Of course it's only 5 inches. Plenty of room in a 36 in tank. You have 31 more inches to spare. Should you put the tang in there? Probably not. You can't ask the fish if its happy and by the time you figure out that it is not you have already stressed it out.
 
Sounds like you already made up your mind to get the fish and are just defending that position. Why ask?
 
When I asked I should have phased my title better true. I left a lot of room for subjectivity. Ultimately I wanted to know if it could be successfully accomplished. A couple posts in this thread have said yes it can be done.

Many post do say I would never do that. That is not constructive educational information. So I may be a little confrontational in that respect I'll admit. Especially when some are down right insulting.

That size tang in that small of a tank is going to get more than just the tang police telling you not to do it.

If you've already made up your mind then there is no point in asking. Picking out a single paragraph of an entire article and then quoting it out of context is not using literature to justify your claims. I you go back and reread that article without biased (looking for what you want to find) you will come to the conclusion that a 3 foot tank is in no way suitable for a 5 inch purple tang, even if it was completely open with no rocks. Unfortunately, it seems like you are going to get it anyway...rather than heed the advice of several knowledgable people. So after this fish kills your other fish then dies don't post a thread asking why because you have already been warned.

When sorting information it is not wise to throw out ten and keep one because the ten you threw out don't give you the answer you want. That's like a two year old trying to follow the footsteps of the kid forcing the square block through the round hole even though the teacher says otherwise.

I'm sorting very little information, but a lot of opinion/emotion. That's my conflict. I have not made a decision. But I take issue with a lack of a academic approach.

You sure about that?

I was leaning away but this article brought up some very good no subjective points about this conversation. Ultimately it's about the ability for the fish to thrive in captivity. This is a full grown 5" purple tang that has been captive for four years in another tank (90). Based on his professional opinion my 40 breeder option is feasible. If I start to see signs of the fish doing anything but thriving I have friends with very large systems that would be happy to take this one.

"Now, what DOES work is to compare the length of the fish to the open water area of the tank (length plus width). Put this into a ratio to facilitate comparisons between tanks. For example, a 4-inch angelfish in an aquarium that has an open water length of 40” and an open water width of 12” would result in a ratio of which reduces to 1:13, an adequate minimum amount of space."

"Zebrasoma are also more attracted to bottom structure."

I'm going to take the purple tang, but not the powder blue.

Also, is it an academic approach to be confrontational?

Wow TP really do exist! :D

Lol. One of the best tanks I have ever seen and that won reef spotlight is Roy Howard's 65g SPS tank and it has a Sohal, scopas, and tomini. And they look healthy and happy. I'm not saying I advocate this just pointing out an example that tangs truly can be happier in smaller tanks I believe it's the fish you get (as they are all different) so almost "luck" you can say and exceptional husbandry but all in all it's their tank.. I've seen a queen in a 45g I would never do that but HK tanks are amazing and they have wonderful happy fish so all in all/ ultimately if the fish is happy who cares?

If you wanna get nitty gritty I've seen happy yellows and bristletooths in a 40g it takes a yellow about 5yrs to reach max and I have never seen a max sized tang yet that wasn't in the ocean/wild

Most likely the tank will come down before you reach max/problems

Ill say it again. Unless you don't put hardly any rock in there there will be very little swim room. If you're planning on doing a reef in this tank the fish will run out of swimming room REAL fast. The ratio rule thing you used earlier is calculated based on a water only tank. After the normal amount of live rock into a reef tank you've probably lost at least 1/3 of your total space and water volume.

Ive seen purple tangs much larger then 5 inches. I have a four inch white tail bristletooth thriving in a 36 inch 65 gallon swimming next to a 5 inch Melanurus Wrasse in my Barebottom Reef. They actually swim together in my overstocked tank and both are Monster's when its feeding time. I think for anyone to argue about taking Wild animals and putting them in any tank thats not the size of the Ocean is stupid. Should you put a larger tang in a 40, maybe not. The amount of filtration you have going, how often you do water changes, what and how much you feed will eventually be the answer if it lives or dies. Some fish just dont make it in any size tank. Goodluck with what you decide to do. Just remember this hobby is probably the most opinionated hobby Ive ever been a part of and when you throw that question out there be ready for the Nay Sayers to come after you.
 
Not to be mean but I love threads like this, someone asks a question "opinion" and when it's not the answer they wanted they get offensive! If you have your mind made up on what to do, do it!

If you are referring to my post I did not once say anything about taking a wild XL tang from the ocean and put it in a 40b. I suggested a smaller tang so it does not reach max size cause a tank life average is 3 yrs (if that) and they never ge the same size as the ocean in captivity

3 years for a tang? If someone is only having their tangs live 3 years, something is very wrong.

No not the tang, ill better explain myself the tank. The tank is is most likely only going to be up for 3-5 years the tang can live up to 20.

So, because the tank may only be up for 3-5 years it makes it okay to put a tang that gets over a foot in a 3 foot long tank? (( using the sohal/65 example you posted above )).

IMO/E, it is best to stock fish that can live their life in the tank that you currently have, and not one that you hope to have in the future --- life can/will get in the way.

If its eating and healthy and is happy why not? Like stated above rock work, other tank mates etc play a big part? All fish are different and if you can keep it happy and healthy it should live quiet fine. As well as I stated above I don't advocate it because I wouldn't put a Sohal in that small of a tank but again if its happy what is the big deal? Husbandry etc come really down to it.. Honestly I bet Roy Howard can keep a Sohal in a 65 more then some can keep in a much larger tank. It's the knowledge that comes into play and a lot of ppl are ignorant and think ppl are cruel because they don't keep a fish in a recommended sized tank. It's annoying how ppl go out of their way to give ppl flak. More tangs die at Petco then an experienced hobbyists tank. And if it is a small tang (1-3") idk why a 40g would be so horrible? Now once they reach size where they need more room and show aggressive signs etc obviously you should put them in a later tank but my point is it will take more time for the tank to get that big from such a small size then the time you most likely will even have the tank up. There are obviously acceptions. Also most likely if you take your tank down you are either upgrading or stopping completely. So you can either put the tang in a bigger tank or sell it to someone with a bigger tank.

Your honestly just mixing my statements around. Never once said its okay. I said it obviously can be done cause it has and no it's no impossible to keep a tang in a small tank as many ppl thing that if they do they will get ich and die.

But I can agree with you on the stock them in a current tank, again I personally would NOT keep a Sohal in a 65g but it obviously can be done. The Sohal also isn't max sized.

Another thing to add is some tangs are different like yellows don't travel as much they stop and go when they do so mainly swimming close to rock where as a purple tang and a perfect example an Achilles travels a lot more.
