the SH in question is H. comes, AKA the "tigertail SH".
it's probably not truly TR...most of the comes are coming out of Viet Nam and are raised in net pens in the ocean. however, the SH from the facility i'm thinking of have been much better in quality than many of the "net-pen" SH at the LFS.
since it has been exposed to ocean parasites, i do recommend treating it prophylactically for worms and flukes.
