I assume it's alright to post this as it's not an assignment question. I've reached assignment 2 on my course and feel very frustrated. In one section it states goldfish can be kept in bowls. Now a fancy goldfish, such as a Ryukin or an Oranda, has a potential life span of 7 to 10 years. They can grow to about a foot long. Common goldfish can grow to up to 13 inches and live for over 20 years. Keeping them in bowls is extremely cruel and this should be made clear in the course. Of course bowls are still sold for fish keeping purpose but any experienced keeper knows this shouldn't be the case.
