This first video shows grass shrimp eating an unknown organism or object. I've wondered if it is a tunicate covered in other fouling organisms or a discarded stickleback nest (we did catch a stickleback the day that I brought this home, thinking it was a tunicate). It is kind of globby in texture. At one point, I thought that I observed a siphon, but now I'm not so sure. The grass shrimp has been devouring the attached material though. I've never seen a stickleback nest, so perhaps if anyone has seen one, they could let me know if this might be one or not. Thanks.

This next video is not exciting, but I find it interesting. It's a bunch of tunicates and a couple live mussels (opened and feeding, I guess). Around the 5 second mark, one of the tunicates ejects something from its siphon. Is it one of their tadpole larvae? I lost track of it in my tank when the current got ahold of it. I didn't observe any movement from it trying to get to a settling spot, but wouldn't that be cool?

The next video is interesting as a blenny is foraging, checking out every nook and cranny around the macroalgae. But, around the middle of the video, decides to enter an oyster shell at about the same time a skilletfish enters, and a brief but harmless battle ensues:

The last video is basically the same spot where several blennies decide to hang out and watch my camera watching them...the three amigos!
