Wrasse Help

do you have a common name for the fish?
nm aka 8 lined wrasse

 

according to LA it is aggressive and reef compatible with caution
i guess it has a taste for crustaceans
edit to add there is a 8 line fairy wrasse this is peaceful and reef safe

They are pretty meek comparatively to wrasses in the halochores genus. They are generally pretty spooky to begin with and often times continue to be sometimes. They can be a risk to crustaceans, snails, and ornamental shrimp (other than cleaners) but typically aren't unless or until they get large. I think you'll find well fed specimens aren't generally interested in shellfish. Although, they are opprotunistic feeders (like if a snail is turned over). Generally compatible with most ANYTHING. However if they are the new guy in town where there are many tangs they can get picked on when they're small guys. Typically they come into their own and become independent, owning some sort of political amnesty in the community.
