Let the identification games begin!

Okay so apparently I'm not as good at this whole identification thing as I thought...all these things are TINY. Like itty bitty micro tiny. Every photo is taken using a magnifying glass. Are these even living creatures or am I finally losing it watching rocks move?
...I probably should try going outside lol

I've numbered the pictures #2 & #3 (guess I forgot #1). Any guess lets hear it!

Some kind of tunicates?

#2 Colonial Tunicates
#3 Not sure, sponge maybe? @KJ

for #3 I tried capturing a video but it didn't come out well, but it looked like it was pulling in a tiny dead pod of some sort. It looked very silimar to a worms thread it uses to catch food but much shorter. Also, up close through the magnifying glass combined with my camera fully viewed in , they look almost like bugs or worms with white balls on either side of their bodies.

I'm here to be no help whatsoever. ;Bored But I would love to figure out what they are, too. Pic #2 almost looks like some sort of fish eggs? ;Wideyed I dunno.

Oh come on. This was your chance - you could've gone with "fossilized dinosaur skin". Just a bit more imagination.

Regarding #3 - What snails, slugs, nudibranch's do you have in the tank if any? These look more like eggs to me. If you come back to this spot late at night when the lights are off - see if any critters are nearby.

...or dinosaur eggs...
