Hi Loachapowa. As Far as I'm aware, Ola's is the only site that has such pictures, but you're more interested in underwater shots right?
The fact is that many natural habitats are not really 'doable' in the confines of a small aquarium, or you would only be able to condense certain features inyo the tank and therefore it would not exactly be 'real'.
For some SE Asian underwater shots and even some short movies if you can find the links, try Nonn Panitvong's aweesome site:

Written mainly in Thai, so a lot of stiff you'll have to find by trial and error, it feature's Nonn's awesome photos and will probably make you want to visit. He did recently post a picture of
Botia kubotai in its natural habitat if you check back down the forum.
