Question about what level of the tank the fish I want stay near?

What level of the tank do.....
Dwarf gouramis stay at?
German Blue Rams Stay at?
Bosemani Rainbows stay at?
Corydoras Catfish stay at?
Neon Tetras stay at?
Bleeding Heart Tetras stay at?
Clown Pleco stay at?

I know that most fish swim all around the tank but when I ask this question I mean what level of the tank are they usually at?

Gourami - top
Blue Rams - bottom-middle. They will usually make their home near some sort of cave, plant or ornament.
Rainbowfish - middle
Cory cats - bottom
Tetras - middle
Pleco - bottom

So you have quite a good spread of fish across the different levels in the tank.

I can only tell you what fish I have actual experience with:

-Dwarf gouramis are top-dwellers
-Corydoras catfish are bottom-dwellers
-Neon tetras stick to the bottom as well

Just from looking at them in the store:

-German Blue rams appear to be middle-dwellers
-Boesemani rainbows are also middle-dwellers
-Bleeding Heart tetras stay close to the bottom
-Clown Plecos, by virtue of being plecos, probably also stay close to the bottom

Three years personal experience

dwarf gouarmis stay top
german blue rams stay bottom
bosemani rainbows stay top
corydoras catfish stay bottom
neon tetras stay top and middle
bleeding heart tetras stay top
clown pleco stay bottom
