I have noticed lots of tiny dots on the glass, took some macro shots and here is what I got;The first photo shows a flagellated protozoa Dinobryon (not harmful).
Second photo shows Ciliates called Stentor (not harmful).
EDIT; I have spotted a few tiny fry swimming in mid-water. I was very surprised. My assumption is that they hitchhiked with plants as eggs. They hatched a few days ago (6 fry). I am curious to see what fish this is :-) I will keep them until they grow bigger, and then, depending on which specie they are, decide will I continue keeping them in this set-up.
