If you absolutely can't fit a canister under the tank, rather than a submersible filter (which usually isn't very good and takes up space in the tank), I'd go for a H.O.T. (hang on tank) filter like the largest Aquaclear. I use a 110 on a 40-gallon stock tank and it does a decent job of filtering the water. A disadvantage is the noise from falling water, but you could either fill your tank up more or add a plexiglass lip to break the fall of the water.
If you can, though, try to make room for a canister.
