It is best to keep the Indian Ocean Hanger alone. If it must be mixed, try to choose ornamental fish that are similar in size, because these types of fish are generally not aggressive, and most of the ornamental fish are more beautiful, which can improve the ornamental degree of the aquarium.

When mixing, pay attention to the size of the aquarium Sufficient, at least 350 liters or more, the water quality should be controlled at salinity  1.020-1.025, pH  8.1-8.4, and regular water changes can improve the health of Indian Ocean hangers.
