Long story short, I'm selling my house while the market is good and moving somewhere where land is cheap and designing and building a new home. It's going to be fairly small, but between downsizing, the cheaper area, and doing much of the construction labor myself, I'll be able to have no mortgage, which means more money for fish!

Building my own house also gives me the unique opportunity to design a built in tank as a feature of the home. For example, a double window tank that can be viewed from the living room and the master bedroom.

I'd like to get away from having a bunch of small tanks and go with one big one. I'm currently considering doing a tank that is 11' wide, 7' deep, and 5' high, with an 8'x4' window on both 11' sides. That's roughly 2800 gallons. This is all in the planing phases so it can easily be changed.

At this point, I'm thinking of what I might want to do with such a tank. I know some people have giant tanks and put tiny little fish in them, but that seems like a waste to me (no offense). I'm also not a fan of species tanks, since It think a good variety is what makes a tank interesting.

I'm also not sure, having never kept any tank over 75 gallons, if some of the "rules" don't apply anymore or as much if you have a very large tank. For example, generally, you wouldn’t mix peacocks and mbuna in a 75G tank, but could they get along when there's a ton of space?

I'm OK with breaking "purity" rules as long as the stocking will work without any major issues. eg, There are some South American fish that can mix fine with certain Africans, but it has to be species specific stocking.

Cheddar’s restaurant often does some bizarre stocking that seems to work. (Does anyone know what the fish are in this first picture?)

So the question is, if this will be my only tank, what would be a good and interesting use of the space, that couldn't be done with an ordinary sized tank?

My first though is to do discus, plus some other large and/or colorful and interesting things in there as well. Most of the recommended tank mates for discus though are small things like cory cats and rummy nose.

With a giant tank though, are there any large and/or colorful things that can get along with discus? Clown loaches? Eels? Turtles, like RES? Small mouth American predators like Blue gill or warmouth? I don't know if haps would be too agressive. They are mild compared to Mbuna, but Discus aren't that aggressive.

Does anyone have suggestions of what other large or feature fish would work well with a large discus setup? Or is there something else exciting that could be done if I ditched the discus plans?

Of course anything has to be safe and healthy and legal to obtain and own in the United States.
 
If I had a tank that size I would do pacus, peacock bass, large cichlids, TSN, arowanas, Niger catfish, rays, silver dollars, datnoids, giant gouramis and maybe a fly river turtle. You could pretty much have anything except for arapaima and alligator gar

How about this as a stocking suggestion it's mostly predatory fish though max sizes will be in brackets
Silver Arowana (60-120cm)
African Arowana (60-90cm)
Ocelarris Peacock Bass (50-60cm) Temensis Peacock Bass (60-75cm)
Indo Tigerfish (40-60cm)
Freshwater Stingrays (45-90cm disc diameter depending on species) Mbu Pufferfish (60-75cm)
Emperor Cichlids (55-100cm)
Fire Eel (60-100cm)
Clown Knife Fish (55-65cm)
Mala Wolffish (35-50cm)
Pangasius Catfish (60-90cm)
Nile Bichir (65-90cm)
And If you wanted something smaller for when the other fish are adults try and track down some butterfly goodeid livebearers, they get 7-11cm and are extinct in the wild so 50+ in your tank would go unharmed aslong as they can get away as the other fish will not waste energy trying to catch small fish if they are well fed
 
Numa's tank thread would be a good one to look at, informative build and imo great stock.

Impossible to say without knowing your lifestyle.

Are you going to do a 100% water change each day, or plan to do a 30% water change each week? That's a totally different stock.

Are you going to travel? For how long? Who will babysit the tank? Different stock.

Are you going to quarantine new arrivals and spend months to grow them out or toss in new fish to the 2,800? What will you do if you need to medicate a 2,800 gallon tank? That may impact which fish you may want.

Do you want plants? Do you plan to have a substrate? Is there going to be decor?

None of this of course addresses the fact that what is interesting to one person might not be of any interest to another person.

Since I am more or less in the same process, my suggestion is to skip species selection for the time being.

Research your tank design and house design, and only the species you personally like, Do this while you decide what lifestyle you are going to have with the tank, and slowly build "must haves" versus "like to haves." Then whittle it down by asking people about each species.

Personally I would pick a "theme" and run with it. I find tanks usually look better that way, than randomly selected stock. Maybe I'm a "purist"... haha.
I would say that would make an amazing amazon river tank. Just some huge pieces of driftwood for décor. 50 geophagus, some peacock bass, an arowana, and some stingrays.

Yeah I think you could do an amazing South American setup thats colorful, interesting, and active. A large school of discus, a bunch of geophagus, a ray or two, and an arowana would make a cool tank. Throw in a couple uaru or true parrot cichlids and that'll give you plenty to watch.
 
Thanks for your suggestions!

Here's a few more details about what I'm thinking since Drstrangelove asked a lot of good questions.

I'd like to do a system that uses as much automation as possible. This house will have a basement, so there will be plenty of room for filtration below the tank. I was planning on doing some kind of bog setup that the water could run through that grows plants to reduce nitrates and frequency of water changes. There are other things I could use as well in the filter room like an algae scrubber, or a sump with duckweed, or something else that grows fast and eats nitrates and can be throw outside by the handful.

I'd also like to have a filter design with an automatic back wash and water changer.

I would also be interested in having plants in the tank to control nitrates and for looks, but that would depend on the fish that are stocked, and it would also need to be something that would look great without pruning since I would rather not go swimming every few weeks to crop and replant. It would need to be something that can grow naturally.

For decor, I'd like to do something down the middle that divides the tanks so you can't see into the bedroom from the living room, but the fish can swim around and through it. Some type of rock formation, either with real rock or Habitat Black or a combination thereof. Could look like a dirt riverbank with embedded branches if we're going with an Amazon theme.

I'm not very familiar with the South American fish, since I've mostly kept Africans and North American.

I have one Geophagus brasiliensis now, although these are supposedly not like the other earth eaters. The other Geophagus species are pretty though.

Of course I will do careful research on everything, but at this point, I'm drawing the plans for the house and trying to decide if I should do one large tank or several smaller ones. I want to make sure I can get a nice colorful and interesting assortment that can justify the size/space of the large tank.
 
You might also want to consider the overall running costs of such a large tank, especially since you said the largest tank you've owned so far is a 75G, which is seriously tiny compared to this monster you are planning...

Eitherway, really hope the project works out for you, as would love to see another large build here...
