I've seen much dirtier glass from other members LOL... But i'm the same way!!! Perfect glass or no pic... Why? they ask... If my stuff looks bad it probably is.. And i take pics daily so i usually wipe it down regularly... I sometimes don't as well.. My kids no longer touch the glass either even the brand new specie tank of "Baaalloooooon fish Daddy" aka to you and i spotted puffers..
