the "thing with three holes" . thats what looks like barnacle. the thing that looks like a sunflower.. I had one of those in my tank a few weeks ago.. it was anout a half inch wide. I looked away for about 15 seconds and I saw my hippo tang swimming away with a smile on his face.. and I never saw the "sunflower" again.. but Im interested to know what it was.. anyone have any clues..
btw you took good pictures.. what camera do you use?

Blue -- no clue but the black looks like some black slime i had hard to tell but is it loose ?

My camara is a olympus camedia digital zoom c-700 ultra zoom!
I have about 15 - 20 of the blue things. they dont move. they have been in the tank since I bought it(already established tank). I have had it for about 2 years
