But what I want to know now is why a generic 30 gal tank is generally seen as acceptable but a 20L, which has the same floorspace, is not. I've gathered from the above post that a 30L is better, but then why do most not complain about a 30?
You're talking about a regular 30 gallon tall, we're talking about a 30 gallon breeder tank.

A 30 gallon breeder tank has the same floor space as a 40 gallon breeder, its just not quite as tall.

So 30 breeders actually have a lot more floor space than a 20 gallon long.
