The Bluegreen Chromis is, as its name suggests, colored in various shades of blue, similar to those of the Blue Parrotfish. The top of its body is dark blue, fading into a light, almost neon blue on the underside of its body, and its pectoral, dorsal, and anal fins are translucent and bright blue. The tail fin, mostly translucent, is bordered by light and dark blue.
To unlock the Bluegreen Chromis, the player must own Pearly Anemone and own any combination of 5 Tangs. It should be unlocked at the same time as the Black And Gold Damsel, Blue Fin Damsel, and the Black Bar Chromis.
The Bluegreen Chromis can be used to reveal the Cross Damsel.
2 Bluegreen Chromis are required to fuse a Pink Smith Damsel, along with 100 Seaweed and 20 Clams.
The Green Chromis, which the Bluegreen Chromis is based on, is surprisingly dissimilar to its in-game counterpart. It is bright green instead of the neon blue displayed in-game, and is found scattered all across the Indian and Pacific oceans, even in the Red Sea. They are found in and among coral reefs, and their diet can consist of anything from algae to unborn eggs to plankton.
