id please,pics included

wow thanks all of your great info. i watched my scooter blennie and he is devouring the pods its like a big buffet to him. he seems really happy. i think i had a large bloom of them they are all over. i have had a prob with micro bubbles recently, im starting to think they are not bubbles and are pods. can they be bad in large numbers. That jelly fish looks nutz, I think ill vacum the hydroids up befor they turn in to jellys, for the sake of me and my fish.
great info peeps thanxs alot.
And a pic of my scooter just for the hell of it. he is and awsome fish. very interactive. lol i just noticed hes got a mouthful.
