That is diatoms, or commonly called brown algae. it is usual in new tanks, during the first 2-3 months normally. It will dissappear on its own. I would rub it off plant leaves but otherwise not worry. The normal algae-eating fish like Otos, Farlowella, Whiptails, plecos will eat this and common green algae. I don't recommend getting special fish just for this, but mention it in case you are planning such fish as part of the tank.
