Help, white spots on aquarium glass

[Nik_oscar]

some tiny white spots have started apearing on my front glass, it looks like tiny eggs but i know it is not cause i have a silver arowana,3 bichirs and 1 pleco in the tank. the pleco seems to be cleaning the white spots but they cme back. any idea what this is ? will post a pic soon.
