The term ''Overrated'' as used above is meaning what are some fish that receive too much attention and aren't quite what they're made out to be. Any condition or conditions can make a fish overrated such as particular water conditions, needing a massive tank, etc. An ex. could be Discus Fish. Everybody loves their personalities, colors, etc. but because of their particular need for soft, acidic water it may make it hard to suit their needs due to your personal city/town/area water. It's also very risky to try and fix the problem by drastically changing your water parameters which could have bad results, and resulting in the lost of your fish. We aren't ''rating'' fish but based on that fish's tank, water parameters needed, and possible tankmates is this fish a fairly easy-medium fish to take care of and doesn't require too much work or is this fish a great fish but the work that comes along with it is unmanageable for most unless i'm willing to devote countless hours of extra time into it. But yes in the end, you will have to technically ''judge'' the fish but not rate it technically. The whole reason I even said ''Overrated'' was because that's a term commonly used for this situation ,and the term rate in it meaning just the common approval or liking of whatever you're talking about on a certain scale. The term rate is closely related to when a person is liking something or someone they're kinda judging it based on their own factors or ''rating'' but since this term is more commonly used in Basketball, Football, and etc sports that's why it has the root word ''rate'' but this isn't what we're doing right now with living beings which are being judged off their own needs, not as we would a sports player being rated on their ability, strength, etc. I hope you understand what this thread means now, if you still don't i'm open to answering any more questions you have.
