What if any "monster" fish could fit in and live for life in a 40 breeder (36 x 18 x 16 in)? 1 solo fish is fine or a school of smaller "monsters".
 
I would say any fish that gets 12" or less. Filter it enough and keep up on wc's and you can have many options. People might not agree with me on this but I would do either a GT, Jack Dempseys, or Oscar, Basically anything you can keep in a 55, because of the dimensions.

Sorry if people disagree with me but with enough filtration and maintenance you could keep these fish happy and healthy.
 
how about a semi-aggresive community? barbs, sharks, gouramis, larger rainbows even though they like longer tanks, or peaceful cichlids!
 
blue dempsey with some bottom feeders

Oscars don't stay under a foot long, they commonly max out around 14 inches and can get to 18 inches. 40 breeders are around 18 inches front to back, so now you have a fish that could possibly end up the same depth as the tank front to back, and is half the length of the tank.

That's some massive water changes you're looking at there, especially if you somehow stuff other fish in with him, and how is that happy and healthy if he can barely turn around without bumping the glass?

Yeah, you could maintain one in a tank like that if you worked hard enough doing water changes every day and put a lot of filtration, but why?

Convicts or other cichlids that size or a little bigger would be a good choice for a 40 breeder.
How about a tanganyikan tank? There's a whole lot of fish to choose from in that catagory and many stay plenty small enough for that size tank. There's of awesome looking tanganyikans.

That doesn't make sense to knock the 40 breeder for being 18 inches when on the Oscar forums everyone suggest 55g which is only 12. Not saying I want to keep an Oscar, but if I did I'd be more worried about the 36 inches over the 18 front to back.
