The green things are algae as one of my friends told me.

Still not sure about the blue items. Any ideas? Maybe a mushroom of some sort?

Blue stuff might be a sponge of some sort. Kinda hard to tell with my old eyes...

The green is bubble algae. Get yourself at least 1 emerald crab per 30G of water and that'll take care of it.

The purple is too out of focus/too small to tell.
