Looks like brown algae. Shrimp would eat it pretty readily.

Diatoms ..They are common in new set ups and eventually take care of themselves ..
May be a couple weeks but they go away just like they showed up ?

If you can easily brush them off the plants with water movement they are totally diatoms. Didn't even think about that.

Is there something I can buy at the store that I can put in the tank that will kill the algae without killing my fish? I thought I saw something that does that

If it is diatoms, it is a bacteria and not an algae. And the thing with them is they will still be there, just dead. Really they are one you should probably just let run its course. But any fish safe algaecide would do the trick for an algae. Hydrogen peroxide works for bacteria, but you would have to turn off your filter because it will also crash your cycle and they would just come back after treatment.

So I should just leave it there? Will it go away? l did a total clean out and wipe down of the tank, rocks, decorations and outside of the heater, thermometer and filter unit. It just came back. It looks awful.
