You missed my last sentence...
ORA
does list their stock with both latin species names AND common names. It is up to the LFS to take the hint, but frankly it has to come from the hobbyist, by demanding that the livestock they buy be correctly identified and labeled with a latin species name and a common if they want to or need to.
Quality Marine is also listing most (80%+) of their livestock with latin species too. I am starting to see other wholesalers list some species with latin names too. Some likely never will, after all if you sell someone an A. sebae it had better be an A. sebae and not an A. clarkii, with common names there is always an argument. Actually had a wholesaler tell me "all sebae are really clarkii and I should know I have been doing this for 25 years, so don't tell me I am wrong!!!!!".
So I do think the supply chain is getting the idea, but the pressure has to come from the money source, the end customer. If a LFS started losing sales because customer refused to buy anything that wasn't listed with a latin species name, you would see a big change and fast.
