tang's in a 3' cube tank?
 

could i have a tang in a 135g cube (34x34x27) or do they need a 4" tank?

i hear sirens......
gimme your tangs

????

Bigfish a 34 inch tank is less than half of the 72 (6ft) requirement for tangs.
Tangs are swimmers and need the tank length to do what they do best, swim. Motor to and fro from one end to the other.
They can't do this in a 34 inch tank or a 4 footer either.

Thanks for asking before you buy one.

Disagree with ya on that one if your place your rock the right way he can go in circles around and round, look at some of those cylinders that you see the tangs motor around and then give her to the other direction..

i'd listen to these guys just think about it a foot and a half to two foot fish in a three foot tank , just to put it simply go live in a fridge box

its all going to depend on what tang you put in there.

and also that the tangs that i have seen seem quite happy too.

I kind of agree with both Mike and Wayne on this one.

Ultimately most if not all tangs will need a larger tank on account for their need for swimming space.

That said a 3' cube theoretically has a larger volume and between gyre type flows and creative pillar aquascaping where they can go in circles and you could probably keep a smaller tang for a while in there quite comfortably so long as the plan is to eventually rehome him to a larger tank. The only difficulty with this plan is that if you don't plan on a larger tank then it's harder emotionally to part with them when they get to a size that's too big for the tank. But depending on the species of tang, some are not as big as others, that could still be a year or two.

There are some tangs though that are simply too large for most tanks even 6' tanks so some research in species selection is of course in order first.

And not all tangs are created equal. A Tomini tang is not equivocal to a vlamingi - one would do fine in a 34" cube (and possibly smaller); the other might have a hard time turning around in a 34" cube with rocks and such.
