He‘s referring to the oscars throat.
The throat is smaller than his mouth, which means everything that he puts in his mouth but doesnt go down his throat will be on the ground.
as long as no one is choking lol

Just got to this thread. It's pretty obvious that the oscar is going to be the main fish, which is doable for life, I suppose. But I can't understand why you seem so adamant on putting other fish with it. Your eventual bio load with a 12-13" oscar in your 75 is going to be pretty heavy and you'll need a good water change schedule to keep everything in measure.

Adding other fish just increases that already hectic schedule, not to mention the issues of will your oscar or won't your oscar eventually eat its tankmates. Rocksor Rocksor earlier point of having a python as its 'tankmate', although very funny, is about as good a piece of advice you'll receive in this thread. You don't need a bottom feeder, and certainly not a plec, to clean up uneaten food. You feed sparingly and any that's left you syphon out.

A single oscar is definitely the way to go imo. A fantastic, very personable wet pet.
I wasn't really factoring in the growth rate of a raphael cat...that's probably not going to work anyway. One fish in a tank is weird to me...first time at it.

I didn’t always like the idea of one fish. After many failed attempts and stupid decisions I eventually learned that sometimes it is the best way. Oscars and other large cichlids are very good solo fish due to personalities.

Sorry to be blunt but.....
I'm one of those that don't believe a 75 is a spacious enough tank for a lone, full grown oscar.
To me its akin to keeping a great dane in a bathroom 24/7.
It is possible of course if ..... in about a year, when its half or 2/3 grown, you are willing to do 40% to 50% water changes every other day, or later on (when its full adult size), you are doing minimum daily 50% or more water changes, to maintain decent, low nitrate water quality.
If you cannot handle that type maintenance schedule, I expect in about a year, you will be posting in the disease section, about how to cure the oscar of hole in the head disease.

I know I've posted pics of my oscar and green severum in their 75gal a lot here and not because I'm a proponent of it. Just showing reality. It's not ideal. I make it work by feeding quality foods lightly, keeping the water temp on the cool side and one weekly fin level water change makes it so nitrates never exceed 20ppm.

These guys have been together in this setup for 8yrs and counting.

X2 on this. Been there and going to say water changes will needed every day to prevent HITH.
