Black and white devil,
Also called a half-demon. Mainly distributed along the coast of India and in the Red Sea region, the catch is small, so the price is not cheap. It is a very mild fish. Only the back half of the body can be seen against a dark background, and only the front half can be seen on a white background, which makes the half-body demon famous, like an elf under the sea.

Aquariums of 120 litres or larger are gentle and can be raised in small groups without harming corals. It is also a fish that likes to move in groups and can form flocks in aquariums. It is best to feed them with a relatively high proportion of seawater (such as 1.025), which can make them healthier. When the ammonia content in the water is higher than 0.2 ppm, they will rot and therefore need to be water quality stricter than other damselfish.
They are one of the more timid species in the genus and can make them nervous when kept with some fierce fish. If there are no rocks in the aquarium, it will also make them always scared.
Omnivorous, animal bait and algae, artificial bait are OK.
