Are these the same thing?

Thanks!

I think I heard somewhere that mysid live in saltwater while mysis live in fresh. Not sure though.

That seems to make sense. Is one better than the other?

Mysidae is a family of shrimp and the members are all called mysids. Mysis is a genus of shrimp within the family. There are FW and SW members of both groups. As far as the hobby is concerned, they're the same animals.

The aquarist really wants the Mysid that comes from the sea/ocean. You don’t want a freshwater mysis shrimp species (like Mysis relicta). Read the label. If it isn’t clear, ask. Get on the Internet and find your answers or send an e-mail to the company. As a generality: the Mysid are the saltwater kind. A 'mysis' is supposed to be freshwater. However, packagers of prepared foods often mix the terms. One of the most common of all these saltwater creatures, found off the USA coasts and used in the USA as part of the Environmental Protection Agency (EPA) water quality test is the organism, Mysidopsis bahia. That is where the "mysid" with the "d" has entered into the spelling 'war.' See Foods for Saltwater and Freshwater Fishes. To make things even more complicated Mysidopsis bahia has been renamed Americamysis bahia. So the confusion continues.

Just get the package that says Saltwater Mysis/Mysid. It has much more nutritional value than Freshwater Mysis/Mysid.

I strongly disagree, PE Mysis is by far the best and once you try it you'll never use another brand. They are much larger then other mysis and all my fish and lots of corals love them.

I just looked at the contents of the mysis I feed.... not even close to PE mysis... I am switching.
