while we can all agree that bigger=better in terms of simple cleanliness, there isn't a reason to consider a 5g tank as cruel for a fish that will generally attempt to claim about 5g of territory. as for the whole "how would you like to live in your room your whole life" argument... well, if my apartment was 1210 times my size and full of yummy food and books to look through, then i probably wouldn't mind especially if i was an agoraphobe. would your boa constrictor now like a salad? we've got ranch dressing.
there are also legitimate financial and space limitations which can lead one to prefer a 5g tank over a 10g. while 10g setups can be had for as little as $50 here in the States, they can be quite pricey over in the UK and elsewhere. a 5 gallon will also (by definition) take up half the space of a 10g and also weigh about half as much. thus, if you only have a bookshelf or the top of a dresser available for a tank, the foot square and 45 lb 5 gallon is probably the better choice than the 2 sq ft, 90 lb 10 gallon. if you can only be 100% certain of successfully keeping the one fish in either of those tank sizes and the fish in question only needs 5g of territory anyways... then why is it a horrible choice to pick the 5 gallon?
