Diatoms?

[Luckydinamite]

Hello everyone! I have a new tank, a little less than 2 months old and I’ve noticed this brown stuff growing in the back while pulling out any extra shrimp my fish didn’t eat. Is this a beginning stage of diatoms? What else should I expect if it is thanks for the help

Also one more thing if it’s diatoms should I begin looking into possible CUC inverts? Any advice is greatly appreciated
