There are plenty of highly popular fish in the trade, some people like an oddity or something rare just because it's not something that you see regularly. There are other fish that you seem to see in almost every tank you look at. I'm interested to know what fish people think are overrated. That is, you think they are far more popular than you think they deserve to be and wouldn't want to own if someone was willing to give you one free (assuming it wasn't due to compatibility or size issues).
For me, yellow tangs and foxfaces are top of the list. They're probably both poplar for the same reasons, bright yellow colour and good algae eaters. I've just never seen the appeal. I love tangs and rabbitfishes, I'd have one (or more) of each in any reef tank I own provided they were big enough, but I just can't get on board with these 2 fish.
