I had a betta in the same size tank without a filter (Shoebox_16 is a real life friend infact xD)
We were doing water changes every other day some times, fed them once a day, and cleaned gravel often - But the film kept returning.
Were both using filters now and have upgraded tank size to 8g and 10g. The film appears to have dissapeared now but who knows, perhaps it shall plague the tank again sometime in the future
