As promised, I finally filmed it (at least in part):
a newt fight
Usually there is a standoff and Otto just runs, but in this case he didn't get away. Last time I saw them fight, Otto's head was fully in Bowagrius's. I wanted to film, but that was a potentially life threatening encounter!
Today also was fun because Muscles was out of his hiding place during the day.

Here is muscles, clinging to the floating island that Casiopia may have abused to escape and then die. The shrimp cling to this or the water lettuce (or the filter arm, rarely) after they shed their exoskeleton during tagmatization (hardening).

Here is his shed! I was so freaking excited. I found the tail, the carapace and ALL the limbs. The front limbs are REALLY bulky, this guy is so damn tough. Nothing in this tank could even harm him. He could be the king of everything, but instead he's a coward who runs like a coward. By strange contrast, Heinrich the whisker shrimp runs the top of the cave like a TOTAL boss, nobody even thinks to bother him but he's small enough to be eaten whole by a newt (one the same size as him was eaten whole). To the left outside the container is what was called a graptolite by the tard that gave it me but it is clearly an ammonite cross section. To the right is what I call a 'cleaning sponge' to help rid myself of algae since snails either accidentally hurt my newts or die to their viciousness. I gotta do some fuckin' work in here I guess.
