I have tried to make these as small as possible without making them impossible to see. I am also going to try and use the attachment feature for the first time.
1) Some brown stuff that's been on the rock pictured since I first got it. Hasn't done anything that I can remember, but I haven't been here for a few months since the tank was set up.
2) ...feather duster? .....pest anemone..? The green thing to the right is my mithrax crab.
3) Blobby thing. I have included an artist's rendering (
) and a short clip. Unfortunately, in the clip it is out of focus- you can still see its "pulsing" though, especially toward the middle and latter half. Look right around the top of the shrimp (the blob is on the glass).
