So yesterday I went to the beach and conveniently found a great patch of noodle seagrass and other fresh green seagrass from deeper shallow ocean washed up in the noodle seagrass. So I had an idea to collect this seagrass with some sand and fresh beach water. So true plants are more hardy than algae which need constant flow and nutrients, so I wanted to see how long this would last and be biodiverse compared to my other saltwater jar which originally was a great mix of red, brown and green algae but quickly became a boring soup of euryhaline copepods and diatom algae pretty quickly. As of today I see tons of tiny blips and floaters of different shapes, at least 2 types of small bladder like snail, amphipods of different colours and shapes, white copepods and a strange crimson copepod, hydroids, zebra looking worms, thin white worms and even a minuscule 0.6cm clam on a spoon seagrass blade. What do you think?

I also saw a tiny tiny feather duster worm! Don’t worry about the black mat and brown debris on the sand surface, that’s just detritus I purposefully added in the jar to add nutrients for the many critters in there.
