EDIT;I would probably post more photos in this forum if I could get hold on to a good but cheap microscope. For that I have to wait.
I noticed those stringy "algae" on the older leaves of the Microsorum pteropus. I guess the plant is leaking some nutrients back into the water column favoring this "algae" if it is an algae

The first and the second photo maybe show two different kind of organisms.
All help in ID-ing these, very much appreciated



I did these shots with a reversed 24mm camera lens, hand hold, 1600ASA
Kind regards, Dusko.
