Agreed, agreed artgecko. I was also taken aback by that tank because marine fish are definitely the most prominently removed from the wild exotic pets. They also have an immense mortality rate, just the facts.

I agree that some exotics require a higher level of knowledge (diet, caging, vet care, etc.) than most "domestics", but that can in part be attributed to "common knowledge". Everyone grew up around a dog / cat and thus knows basic info on diet, care, etc. and vets are easy to come by.
This is particularly true. Going back to what I said about cats, it all boils down to culture. Our culture knows and understands what dogs need, but for some reason we fall short on other species. Cats are seen as independent, but in the past most people let them out of the house. Now that many are (rightfully) indoors, they are in a very large enclosure, and they still need enrichment like a zoo animal. Some individuals should have outdoor access that is supervised or enclosed. I think domesticated cats need just what their wild counterpart would need (Africa wild cat). If you look up that animal you will see physically there is no difference between the two species at all.
