The juvenile Cross's Damsel features a narrow blue stripe that is running from above the eye and ends at the end of the caudal fin. With its bright reddish-orange body color, it adds a splash of fresh red color into the aquarium. As it matures, the coloration fades to a dark grey-brown color and the blue stripe shrinks towards the eyes before disappearing. The Cross's Damsel is considered an easy fish for a beginner, and needs its own territory unless kept in a larger tank. The Cross's Damsel is an omnivore and can be fed on all kinds of live, frozen, and flake foods and algae, and also is best to feed small amounts several times a day. As the Cross's Damsel grows, it becomes more aggressive and territorial, which makes it very difficult to introduce new similar damselfishes. Although, there is no distinct feature between male and female, the Cross's Damsel has been bred in captivity, and should be kept in a tank not less than 15 gallon. The Cross's Damsel is hardy and can tolerate adverse water conditions in a new aquarium, which makes it a very good addition to any reef tank. In order to keep the Cross's Damsel at peace, it is necessary to provide them their own rock work and hiding places. Due to its small size, the Cross's Damsel can become food for many fishes such as Eels, Groupers, Lionfish and Scorpionfish, Seahorses and Pipefish, Sharks and Rays, which should not be housed with the Javanese Damsel. The Cross's Damsel thrives well in 72-78 degree Fahrenheit and pH between 8.1-8.4, and is recommended for peaceful community aquariums. The Cross's Damsel is reef safe and doesn?t bother any corals present in the nano reef tank.
