How to tell
 
the difference between a blue lobster and a blue crayfish? We have them at the store, but they are virtually the same.

Lobster=marine
Crayfish=freshwater

They're still the same if you are talking about the freshwater crayfish that closely resemble the lobsters but IMO, for the freshwater vocabulary, crayfish would be the better term.

Hm, so then all of the ones that we have in our tanks must be crayfish then huh?

I doubt lobsters on the marine side would ever be kept considering they are far too destructive and too large for the private aquaria.

Yes, it is almost always guaranteed all those creatures in your shop are crayfish. And again, crayfish are almost always available in pet shops wherever you go.

Insofar as fish store nomeclature goes, they're the same thing. Now granted, there are different species, and if they're freshwater they are properly crayfish and if they're marine they're properly lobsters, but fish stores will call them one or the other without regard to actuality.

I believe that the Blue Crayfish is known as the Blue Lobster in the UK. Not sure why this is, as other rightly point out it is indeed a crayfish. Possibly it's becuase Crayfish had a bit of bad press recently after American Crayfish escaped from fish farms and are now merrily decimating our native population, or possibly because we Brits aren't so accustomed to hearing about Crayfish so much. Don't know, anyone who does please chip in.

Oh, and if you've got a spare tank, it's well worth getting a Blue lobster, Mine is facinating, really active and, as (s)he's got older, a really lovely blue colour. Just don't let the little sods escape!
