Filtration Per Oscar

[michaelh]

Hi guys. Just wondering if anyone knows roughly how much filtration/hour each oscar needs.
Im talking about keeping multiple adult oscars together btw.
Is it possible to just say each oscar needs X LPH?
Surly tank size doesnt matter (other than aggression) as if your filter wasnt up to the job even a 10k litre would eventually become polluted.
Just like to add i have no adult oscars but 3 bubbies and 3 4' tanks but their all in 1 together atm with no issues.

Ummmm...... What size is your tank?, I dont think a single oscar needs a certain amount but I would recommend a filter rated for 100+ if you were to keep more than one in a 75 gallon

Need to know tank size, i think it does matter, if it was in a smaller space then more filteration would be needed.

Really? Hhmmm i was just wondering tbh. My biggest tank is only 4x2x2 hence the other tanks prepared lol.

Rated at 100+what? GPH? Or 100 gallon tank? At the mo im running 2 fluval 305's and an internal APS 800LPH. 2800LPH in total with alot of media lol.

they're babies so of course they'll be getting along now. But when they're fully grown, you'll need a bigger tank to keep all 3 of them together. They'll get a foot long, sometimes bigger. For 3 adult male oscars I'd say a 125 gallon is a minimum. And that might even be too small. Cichlids are territorial and need their space. Filtration isn't a huge issue as long as the filter media is mature and your ammonia and nitrite stay at 0.

my 305's are rated for 300 litre each so thats like 80 gal.
Will 2 of these alone handle 3 oscars?

Except 75 gallons isn't big enough for more than one.

I think that they can

I have agree with you, a 75 is only big enough for one, I was just using that as an example

I have read 50 per oscar MIN but thankyou both. Just looking for examples so i know how to/what to filter the other tanks with for when their adults.
Why do people say they need that much space? Is it for them to move? I know they can reach 16"? Or more aggression?

Big fish need big space. And all cichlids, even angelfish, will claim territory, and battle with fish who try to intrude. They can be especially aggressive to others of their species. My cichlids only care about other cichlids. Especially others who share their name. Unfortunately, with a small tank, there just isn't enough territory to claim. in a 75 gallon tank, 2 oscars will always be 2 feet or less away from each other. With 3, there will be almost no space. That's why they need a big tank.

50 gallons per oscar would be an okay rule when keeping 2 or more oscars. That doesn't mean you can keep an oscar in a 50 gallon tank, though. It's kind of like that 5 gallons per discus rule, that's okay when you're keeping 6 or more discus, but that doesn't mean you can keep 1 discus in a 5 gallon tank, or 3 discus in a 15 gallon tank, etc.

But remember its not just about volume its about dimensions, I think a 48x20x20 could house one oscar on its own without any tankmates and thats only 69 gallon, if I just said I was putting an oscar in a 69 gallon, ya'll freak out.

Dimensions are much more important than volume.

Thankyou for the info.
Im quite aware of their size and reputation(i belive overated so far) just wondered why particularly so large. Seems just to be a combination of both factors. Thankyou for sharing your knowlesge and info though mate.
My oscars 3.75",5.5" and 6.25" (smallest one was brought smaller and introduced first)all get along perfect SO FAR but i am definatly ready to deal with any agression or anyone just being left out or becoming timid.

I'm talking about standard dimensions. high volume tanks tanks with "tall" dimensions are pretty rare, and with reason. Tall tanks are made to be space savers, and high volume tanks take up a lot of space, anyway, and for the most part, tanks with a lot of volume are bought by more knowledgeable people. Not to mention, if you had a 100 or 150 or 200 gallon tank on a small 4'x2' or so foot print, that'll definitely do a number on your floor. That's a lot of weight on a small area. That's why it's easier to talk in volume specs with big tanks than it is with tanks that are like 5-30 gallons which come in all shapes and sizes.

Totally agree unless talking large groups of small fish. But thats not this subject lol.
