Rocket hangers can be mixed with other fish. While rocket hangers are fierce against other hangers, they are friendly to other fish. Rocket hangers like to attack other hangers, even if they are much larger than their own size, golden hangers or coffee hangers still dare to catch up and bite, and even small angelfish are the targets of their attacks.

Brain coral and some sea anemones are best not to appear In aquariums with rocket hangers, although they do not eat corals, they like to peck at those beautiful jelly-like coelenterates, so these corals are tricked into not being able to unfold normally, affecting their healthy growth.

The maximum body length of the rocket hanging in the aquarium can reach 13cm. The color of the rocket hanging juvenile is composed of yellow, blue and white. In adulthood, the color is fixed, the tail turns blue, and the dorsal and anal fins are golden-edged. There are small golden spots above the eyes and a golden circle just below them.
