Minnow

I'm afraid I can't yet say that I've figured out how to take a passable photo through glass. But life in the aquarium is otherwise going swimmingly.

My two minnows and one caddisfly larva were soon joined by ten tiny tadpoles (who they promptly ate) and seven snails (who got busy cleaning the glass). And Friday I figured out why one of the minnows has a tremendous belly --- that fish finally learned that flakes on the surface are yummy and is now eating them as quickly as they appear.

Chemically, the pH is still high (8.0), but the biological filter is obviously doing its job well because there's barely any ammonia and no nitrite or nitrate in the water despite daily feedings. Perhaps I should add a few more fish?

Using a second piece of glass behind the fish is a trick the late Dr Wm T. Innes used. With this piece of glass, you can bring the fish up to the 'front' of the aquarium so they are in one focal plane. Reflections are still a problem, though. Cheers!

If you put something dark behind you, like a blanket or a bedsheet, then you can get rid of those reflections.

Add a circular polarizer to your lens. Should take care of most reflections with some adjustment.

Your big-bellied minnow might be pregnant. If so, the babies will likely get eaten, but maybe a few will survive to further populate your tank =)
