- Start date
Don't post the 14 second one with a supposed 18 inch Oscar that lived it's whole life in a 40 gallon yet turned without touching front or back.

Just my opinion, but I think 150 min for a couple Oscars, maybe 125. I've got a couple in my 1000g and they are pretty damn active. Can't imagine seeing them in anything very small.
This guy (not mine) had to be about 18". That's a 75 g.
The thing is nobody wants just an Oscar. They want an Oscar, another cichlid, a school of dithers, maybe a Pleco. I've tried this in a 90 (minus the pleco); I wouldn't do it again.
There's a poster on here who writes about how a pair of JDs in the wild will defend territory the size of an SUV. That's the amount of space they evolved to inhabit, to seek, to fight for. What do we mean when we say a much smaller space will be adequate for Oscars? By what standard? It's not clear.

Fish stake out large territories in the wild because of food or guarding their young. If our fish aren't having to worry about food because they are getting more than they need from us and you aren't breeding them then you don't need a solo oscar in a six foot tank unless you have another cichlid and then they will scuffle over territory because of competing for the food that we give them. I think a well fed fish will be less territorial. JMO

75 gallon is 18" wide (externally)
This is the side view of the tank
The fish touches neither side internally and has observable space.
Clearly not close to 18".
agree side angle of tank and clearly not 18, but appears to be rather close...... it has about an inch in front of him, and from what i can tell, has no room behind it, as the "rooom" behind could / is just a reflection of the glass + the tail looks to be a bit bent, so I would guesstimate this fish to be around the 17 inch mark..... than again, this could also be a 15 inch wide 55gallon tank like i have in the garage. so who knows
I would say a 75 for a full grown oscar is good. he/she could probably live in a 55 but If you want him to thrive and be happy go with the 75 or larger and frequent water changes..
