Hi guys this might be a silly question, but i was wondering if i had enough ventilation.

basically the reason why i was asking is because my glass is always fogged up (not all the glass, but a good percentage of it), i do have a small water feature in there, so is this just due to the humidity, or do i need to add more ventilation, i do have some, but i can add more if need be

if need be i can add pics
