What a gorgeous fish!
They are beautiful, aren't they? I love the name "fairy basslet." Inhabitants of coral reefs in tropical and subtropical waters around the world.
The aquarium store owner told me that fairy basslets were too aggressive to have more than one of in a tank at a time. Then I saw about 100 of them in a tank together at a wholesalers. So now I will get 5 or 6 at a time, no problem at all.
