The Cross Damsel is colored mainly orange, fading to a slightly lighter shade towards its underparts. A thick stripe, made up of a large light blue section and a smaller black line on top, makes its way from the Cross Damsel's eye to its tail fins, with an upwards curve in the middle. Its pectoral fins are colored a very light orange color, and its anal and adipose fins, mostly a translucent orange, are bordered by the normal body color. The caudal fin is colored and designed much the same.
To unlock the Cross Damsel, the player must take 3 pictures of Damsels. For some, it may be required to share the pictures as well.
2 Cross Damsels are required to fuse a Black and White Chromis, along with 100 Seaweed, 20 Clams and 5 Sea Urchins.
The juvenile Cross's Damselfish, the Cross Damsel's real-life counterpart, is colored almost identically to its in-game replication. They are found around Papua New Guinea, the Philippines, and Indonesia, and never dive too far beneath the surface. They will eat both plants and small animals, and are sometimes found in aquariums.
