65 Gallon - Silent Oscar Tank?

Hello everyone
I just finished up an african cichlid tank, and because I have the multiple tank syndrome so I'm already planning a 65 gallon for an Oscar. I saw one at my lfs and I automatically wanted to have one.

I want this tank to be on my living room as a display tank so I need it to be as silent as possible. As a filter I have a number of ideas but since overflows are kinda noisy I am limited to internal filters.

I haven't decided which internal filter yet but I don't want to use an air pump driven filter because they are usually pretty loud. I have no hurry but I am a bit concerned that without the airpump the tank will lack oxygen exchange. Should I be worried?

Any suggestions in general about Oscars would be appreciated to. I don't know much about their requirements

Thanks!

 

Maybe something like a Seachem Tidal, some type of canister filter (they are supposed to be quite according to the other members on here) or multiple internal filters that won't get destroyed by the oscar if you decide to get one.

65 gallons might also be too small for a full grown oscar depending on the dimensions, since they can get to 12-14 inches, sometimes 16 inches or more.

 

I have read that they get to 12 inches in average and the absolute minimum tank is a 55g. Of course the absolute minimum is not ideal so I was planning the 65g. If I need to I could do a 75g.
I am from Peru so most cannister filters are not easily available to me. Do you think a corner hamburg matten filter could work? or the oscar would destroy it?

That could work if there is one in each of the back corners, but those are great for only biological filtration, and aren't good for mechanical filtration.

 

Get two aquaclear 110s

 

I'm not much help with the bigger filters, but I will chime in on the tank size. I have never had an Oscar but my friend did have one and it was like a puppy. They are extremely active, and need space and toys. She kept her Oscar in a 150 Gallon and he had enough room in there. I have had heard other members on here say 100 gallons and that seems appropriate.

 

I will try to get a 75 gallon, the bigger the better I supose.
As for filtration I'll think about it more but I think I'll go for two corner matten filters, that way I can cover heaters and stuff.
As for decoration I enjoy natural aquascapes, oscars like decoration or prefer an empty substrate?
