Our tank's biology up close

Scraped off a little green film algae off my front glass before I cleaned it all off with my mag float. Almost all entirely Tetraselmis phytoplankton and various diatoms.

Those Tetraselmis LOVE light. If I kept focus on one spot long enough they would start swarming over to it and chaining together (film algae...). Also found Licmophora (triangle shaped diatom) that was newly forming and branched together still. First time being able to find that.

"Description: Epiphytic diatom, cells grow on a common stalk that is attached to rocks or algae..."

You've got some great images in this set. What kind of copepod-mysid-whatever is that in ats-sample-20191127--0033?
