How big can oscar get

  • We are currently upgrading MFK. thanks! -neo
They can get over 12", but normally the females wont.
This is new information. Any other references to support the idea? I would enjoy believing this to be true.

lol, I found a link or two that supported the idea, but then it's a mix of things. Can't be determined by looking at them, can be, females are more colorful, males are more colorful, etc.

What I have found out with MY experience with Oscars. The female I got three years ago an 1". As she grew she grew long and slender, and stopped a year ago at 12". How do I know that it is a female? She has a large 'vent'. ;)
Now, the male is a rescue, apparently was purchased 4 years ago at 2", and grew to 14" over time. When he stopped or if he is still growing? Not sure. How do I know that it is a male? You can't even see the 'vent' unless I took him out and really tried to find it, lol. He is 'taller' in height then she is. She must be 4" high and he has to be 6" high. Now, I have had people say, "Maybe the male grew up in a larger tank than the female, and therefore grew larger!" Nope, both have been housed in a 55-Gallon all their life, although the male is in a 60-Gallon, soon to be a 90-Gallon. ;) The male also has more red coloring around the face then the female does, and I believe that they are both "Common Oscars" although the previous owners said he was a Tiger, but I just don't see it. And the male is MUCH more aggressive. Attacks his own reflection randomly, as the female does not, lol.
Anyway, that's what I have been able to observe.

You and just about everyone else on the internet. Nothing personal, but as I said, I'll believe it when I see it.
Alright, just measured him, and I was off by an inch. He is actually 13", lol, but still no pic to prove it yet seems how it is...12:43 am, lol, I'll post some later. ;)
 
Also how do you measured them tail fil or just body?
 
I am not a big fan of oscars and don't claim to have any good information on them. I was given a mature oscar about a year ago. It had grow up in a 75 gallon tank that was poorly maintained. It now lives in a well maintained 210.

Its fins are freakishly long. I suspect its one of those odd ball "long finned oscars" or at least a hybrid of one. Anyway.... WITH its long fins, it might be 12". Maybe. Probably not though.

I see thread after thread about 16" oscars and wonder how I got such a runt. Do I have a runt or are you guys all full of hot air?
 
It's just like with people some are tall others are short. Not all fish grow to the full size and some grow more then the average. I'm sure oscars can get to be well over 12" but not all just like how not all men grow to be over 6 foot. Genetics play a role in how big a fish can grow as well as enviroment and good food.

Sweet, I wasn't doubting you or anything, I just find it strange that considering that oscars have been one of the most popular cichlids in the hobby for years, and considering how many websites and individuals claim to have oscars considerably larger than 12" I have never seen a single pic of one on a tape measure to prove it...
