I couldnt agree more that gars need width more than length and no i am not saying you should keep a 3" gar in a 150/180 which is why a put "(once they get large)" that you conveniently missed out, and a very wide tank i would deascribe as a very large so a 5x4 in my mind is larger than an 8x2.5x2, i stated 8x2.5x2 initially because in my mind it is the required length for such a large fish (you seem to disagree, fair enough) but only 2.5x2 because that is what you could get away with (minimum) but an 8x3 0r 8x4 would be better and "very comfortable".
And very comfortable were your words i certainly havnt confused it with minimum.
I do not wish to start an argument i gave the guy my advice, what i would do if i were to purchase a gar if you disagree fair enough would it not have been better to just give him your advice without quoting my oppinion on the subject, the last thing this site needs is more arguments. Thats one problem with forums, there are far too many big ego's and conflicting oppinions and it allways ends up with yet another argument.

I appologise as i seem to have offended you, really i didnt intend to cause an argument.
