I found out my camera has this microscope-like mode. Here's some examples:

Just wanted to say it is now empty of fish. It isn't heated and it's pretty chilly (like about 68F most of the time). It also only has a soft white bulb (wrong temp I know, but its all I had) and it does get sunlight, although only when I open the blinds, but that's only because it has nothing in it. It has no plants and some ponds snails, and algae, the kind that sticks on the acrylic really bad lol. So other than an rcs tank (for which I'd need a heater for) any suggestions?
