Tangs for a 150 cube?

I have a 150dd which is 4' if you measure diagonally and 200 gallons including sump volume. I'd like to have a powder brown and yellow tang. Is like a powder blue instead of the brown but they seem to need the room more than the brown. What are your opinions? currently there's
Starry blenny
Scooter dragonet
Small diamond goby
4 hutchi anthias
Black leopard wrasse
Yellow fin flasher wrasse
Dot dash flasher wrasse
Longnose hawkfish
Orbic cardinal
2 firefish

I added a little vinegar to my kalk to put off switching to 2 part a little longer and my phosphate dropped to 0. I never get nitrates so I'm looking to have alittle more of a bioload to keep the lps happy. And the rockwork is pretty open.
 
As long as the rock work is pretty open so they have paths to swim I would think you should be fine. I have a Tomini and an Orangeshoulder in my 100g cubish with a 4 foot diagonal, it is very open and the Orange should has a nice figure 8 through the whole tank that he likes to swim.
 
I advise against any powder tangs for a 4' tanks. they really need 6' to be comfortable given their swimming behaviors. for your tank, you should be looking at bristletooth, kole, or tomini tangs. they only get to around 5" and will fit a 4' tank fine.

I agree. its the swimming room, rather than the water volume that is so important to long-term tang health. Finding fish to occupy the upper areas of cube tanks can be tough; they sure look great in the right spot,though. Some anthias are ideal fish for cubes, IMO.
 
Actually the phrasing of the original post makes me wonder if this tank is even 4' long, given that he's talking about the diagonal.

Good catch! I thought only TVs were measured diagonally. With his ears, if Pres. Obama was measured diagonally; he'd be about 7'4". Without doing the precise math, wouldn't this make the tank less than 36" on a side? At 64, I still remember some geometry.

Edit: just looked at Glasscages; they have a 120 "cube" that's 30x30x31. 48" diag= approx. 34" length, I believe.

Yeah it is a 36" cube and the fish could swim 4' straight or close to it. I appreciate all the feedback, I recently had to remove my clown fish because they got so aggressive when they laid eggs that they killed the female flasher wrasse by stress from harrasment. I do not want a tang that's aggressive because he's in a small tank taking anything else out. I don't like the tangs mentioned but I'd that's my only choice I guess take it. No yellow either huh? I was on the fence with them and they're aggression issues also.
 
I think, long-term, you're going to have problems with any tang. They simply need the space to swim. One flick of a pec fin can send them 3 feet. Many tangs are very hardy fish and may stay alive, but they can't really thrive without space to swim. IMO & IME BTW, if a fish can swim 4' by going from one lower corner to the opposite high corner; that's really stretching it. How would you train a fish to act so unnaturally?
You could get a round tank and they could swim in circles for miles; even decide which way they'll swim by clipping of a pectoral fin!:lol2:
