Sai, i am most impressed with your firstly, calm observation of animal life (read spiders) and appreciation of their role in the world around us, second, complimented by an absence of obvious bias in favour of fish/plant/invert that many hobbyists have. In fact, this thoughtfullness and consideration for other creatures is the halmark of a true nature lover.
In fact, i confess i am even more interested in your hood idea now, can i now expect u to photograph the ootheca for us?
My angelfish are talented spider/fly/gnat eaters. I wonder if yoru hood makes it possible for this live food to spontaneously colonise it, and generate suitablu regular high-protein diet possibilities for no additional effort on your part?

Since the thread is already jacked, as Ishaan has most helpfully accepted (thanks Ishaan, i will add an extra umbrealla sedge plantlet for you in yoru courier now), i am sure a moderator will not come barging in to break us up. He will indulge us, in the interests of conservation of mother nature in aquarium hoods themsleves, when possible. hehe.
