Tank Size: Width Or Length?

[Mako Man111]

I was wondering what would be better for a single oscar, a 58 Gallon 36"x18"x21", or a 55 Gallon 48"x13"x21"?

I've read both. Some say they need more length, others say width.

youll actually find that most people say a 75g is the minim for an oscar.


the 36" isnt really long enough and the 48" not really wide enough IMO.


a 75 is more like 60x18x18 which has plenty of space in every direction.
