Im just curious how long should a tank for a single Oscar be? I am assuming a long tank would be preferable over a tall.

I think 75 gallons for 1 adult Oscar. No tank mates

Yeah I know they need 75g for a single. I am more interested in how long the tank should be.

Not sure how long, I think as long as it's 75+ gallons and is a couple feet wide, it would be fine.

come get me tang police!
48x18 would be my minimum for a single fish.

4ft long and 2ft wide I would say (so 48 x 24 inches)

Sounds about right (minimum)

48x24 is a very uncommon tank size. 24" wide tanks in general are not common store fodder.

In America probably but the UK is different. Our tank dimensions seem to be totally different than yours. Always puzzled me why as I know our gallons are different but we both use the same measurements for length.

I had an oscar in a 62''x12x12 75 gallon. Doesn't work well because they're jumpy. I moved it to my 120 gallons(I had 2 of them).
The ideal Minimum is 55 gallons semi high and long.

My buddy got a tank like mine, its a 56 column and only 30" wide. I told him I didn't think it was going to work but just wanted to make sure. I don't really know the swimming habits of Oscars.

I don't know about the size, but i know oscars out grow 55 gallon tanks in a year or two

an oscar can work in a 55gal for a little while, but since the fish can get 14+ inches and the tank is only 12 inches wide inside it doesnt work well. 75/90 gallon are a little better suited since they are both usually 18 inches.

a 55 gal is 48'' O_O
And red oscars get 12'' fyi.

Yes, 48 inches long, 12 wide and 21 tall for a 55 gallon. the 48 inch part isnt the bad measurement for an oscar.
a heathy oscar can get well over 12 inches, dont believe what petsmart tells you.

There is no petsmart in canada
I did a lot of research, red oscars can go at most 14'', only tigers and ect can got a bit more. But only in optimal conditions.
But if you look, a 75 is 48" x 18" x 21" and 90 is 48" x 18" x 24"

red oscar and tiger oscar are the same fish, just different color pattern. Astronotus ocellatus

They are, but it depends on the way they were bred. Usually, red aren't wild but domesticated.

sorry do derail thread op, in my opinion, one oscar would be ok for life with a minimum tank footprint of 48x18 inches.
