    Any healthy reef aquarium has a continuous growth of green micro algae on the inside glass panels, which we duly scrape off with the magfloat whenever it becomes visible enough. Snails, as well as some fish like the lawnmower blenny, eat these algae.

    Here is what I am talking about.

    I was curious as to what exactly this layer of algae is comprised of. So I took a sample and put it under the microscope. Magnified to the same level one would view red blood cells under, it is clear about 95% consists of Euglenoids (curious part plant part animal organisms that can photosynthesise and swim around) and about 5% of various diatoms, mostly Closterium setaceum.

    Love it!

    Can you show some pics of your microscope setup? The kids have one of those Intel usb microscope jobbies with built-in CCD camera, but the optics are rubbish.

    On the left is the tracks from snails, as they tend to go left and right in small motions as they move forward, leaving a fern leaf type trail. On the right is most likely a Lawnmower Blenni and his kisses left against the glass.

    I made a mistake in my ID of these organisms. Apologies. The Euglenid is an Eutreptiella sp., and the diatoms are most likely Cylindrotheca sp.
