Images 001 and 002 are of the algae i'm not sure about. The rest are just of the tank and our fish. also if anyone can tell me how to insert the pictures right into the post instead of linking it that would be helpful.

You just click the little picture icon at the top of the message area and type/paste the location of your picture. Like this...

And like this...

The first looks like just a diatom bloom. New tank, I'm guessing? If so, it's a normal thing that happens, and some snails will make quick work of them. You can blow it off the rocks with a turkey baster, but it'll just come back. Eventually it'll burn itself out and go away. Kind of a "new tank rite of passage" we all go through.

The second though is strange. First thought is cyanobacteria (red slime), but only because of the color. Is it kind of slimy and covers the rock in a sheet? Lots of bubbles in it? I don't see any bubbles, and it doesn't look slimy... that's why I'm a little confused. If it is cyano, it usually means excessive nutrients in the water (nitrates/phosphates) and/or a lack of water circulation.
