Stocking for three foot tank?

[Tkeeper]

Hey people just wondering what are some stocking idea's for a 3 foot long, 1 foot deep and 1 foot tall?
I think the tank is between 20 and 25 gallons from what I can tell, can anyone confirm this?
As for the kind of fish I would prefer a shoal of aggressive fish or one or two relatively large (for the tank) fish..
I'd really like something like a flowerhorn but of course my tank is far too small...
So can suggest a fairly large and interesting fish or a shoal of aggressive fish for my tank?
(And no marines!)

If your interested in cichlids, convict or firemouth might work. Other large (for your tank), but not necessarily aggressive fish include African Butterflys, Crocodile fish, Upside Down Cats or a Celebes Half Beak (not really that large, but cool in my opinion).

For aggressive schoolers, you are somewhat limited for your tank size, but semi-aggressive fish include Blind Cave tetras, Buenos Aires tetras, Colombian tetras, or if you really wanted to, try a small shoal of exodons. Just don't try to mix them with tankmates. They are nasty.

ba tetras+a small cichlid would work well ,maybe even a bn pleco

For something a little different you could have around 6 spotted or figure of 8 puffers. I used to have 3-4 in a 2ft tank & they were great
