The Purple Queen (Pseudanthias pascalus) is a small fish only found in Endless Ocean 2.
"It is definitely worth trying to see schools of this beautiful deep purple anthias near coral reefs. Of you get to see one up close, you will find that its mouth is more pointed than those of other varieties."
The Purple Queen can be found in Gatama Atoll at coordinates A-7, A-8, B-3, B-4, C-6 and F-2.
These fish swim about somewhat slowly in large, loose groups. They like being fed.
