That's like....when I clean my glass on the front door the dogs are attracted to it like magnets and I think...Why bother doing it??:lol:They must like it clean too??:lol:
Sorry, not fish related :dk:
As for the bns, they can't scrape off spot algae themselves, so even though you cleaned the glass you have probably left behind loads of freed up particles that you can't see and they can eat.
