It's often said that a larger tank (body of water) is more forgiving than a small tank, but I question it. All things being equal, a larger tank is likely going to have more fish (a larger bio-load) and if you're using additives, you're likely going to using proportionately more....so it's kinda the same....just bigger!
The pros are a much bigger display, more and potentially larger fish and larger plants (my 24" Amazon Sword just wouldn't work in a nano tank.
The cons are that the bigger tank, filter(s), lights, amount of substrate/plants/stock/ferts... is gonna cost more. It's also gonna require somewhat more ongoing maintenance. More glass to clean, more water to change, more filter media to deal with, plants to trim/replant...
And high tech vs. low tech means increased cost and effort to maintain.
Having said all that, if you're just dipping your toe in the hobby, smaller is better. Often newbies lose interest and tanks and fish suffer until folks give up. However, if you've been in the hobby awhile, I feel bigger is better as there are just more things you can do.
In my youth I had 10g, 20g, and 29g tanks, but feel my current 60g, in many ways, out shines them all.
As mentioned, that's not to say you can't have a really nice 5g tank. When I was a boy, my mom had a 5g slate bottomed metaframe tank with a bubble up filter. She always had floating anacharis and 5 of the most beautiful, healthy and long lived fish....and this tank rarely saw a partial water change and was topped off with tap water! .... I guess the floating anacharis were a nitrate sponge?
Tank On, Mike-
60g Marineland Community, Finnex Planted+ 24/7, Silica (pool filter) sand.

What came first, the chicken or the egg. It was the egg, but not the egg from a chicken.
