I'm fairly sure I've Identified these items correctly\n\nPic1: Hydroids(Gather fairly harmless and will die out)\nPic2: Spagehtii worms(Harmless)\nPic3: Coepepods (TONS all over the glass, the picture is representative of my entire glass surface)I could visually see only a couple move..once I got my camera in macro mode and zoomed in I could see tons of them moving. These are good. I've been waiting for them to show up. I didn't realize what they were for about a week till some got big enough for me to see move by the naked eye.\nPic4: Coralline Algae (good) I got it growing on my glass and ALL OVER in my algae scrubber.\nPic5:Spirorbid worms(harmless)\n\nTank born on Nov 1st 2009. I'm happy with the Coepepods growth I really want a mandarin at some point. I'm not sure when to determine I'm at that point however other than others rough approximation of time frame.
