The fact is that fish produce a huge amount of waste, because they need a very powerful filtration system. And most importantly, goldfish can grow up to 25 cm in length and live up to 20+ years. Just few people suspect this, since these fragile creatures most often die at a young age, before even growing up. And all because of the wrong aquarium.
