I recently asked advice on which tank that is no longer than 36" long I should get, and it seemed most people favored the 40 or 50 breeder (both 36"x18" and either 16 or 18" tall). I could not find a 50 in the stores, but did find a 65 with that same footprint, but 24" tall. I know I have read to get the biggest tank you can fit, but I have also seen posts that say taller tanks are not the best. So although technically I guess I do have room for it, do you think this would be more trouble than its worth? Since fish use horiztonal space more than vertical space, would this be worth it, or should I just stick with the 40? I'm sure I'd have plenty of room in the 40, but just wondering if it would look funny being so short. I am just going to have a peacful community tank, with a couple groups of schooling fish, and maybe a couple gouramis or similar type of fish that size.
