The Orange Line Chromis is also commonly known as the Spiny Chromis, which as a juvenile is blue in color with a broken orange line running horizontally from the gill plate to tail. As it matures, it changes color to a brownish appearance with a white tail. Being a hardy saltwaterfish, the Orange Line Chromis makes a great choice for a beginner aquarist and a healthy tank inhabitant as well. It is generally a peaceful fish, and that adds a dramatic effect to the tank. The Orange Line Chromis has a life span of 8-15 years in an aquarium with good water quality. It should be given a varied diet that includes meaty items, herbivore flakes, and frozen preparations. Also, vitamin enriched foods helps it to maintain its color on the body. The Orange Line Chromis should be kept in a tank not less than 10 gallon, and since it is a peaceful fish, it is considered a reef safe species. It might become territorial and may show aggression towards other Damsels, but make sure to add lots of rockwork or corals to break up the aquarium into several smaller territories. The Orange Line Chromis should be provided with ample rock work, and do well in a community tank. It will remain in its caves or crevices and comes out only when it will be fed. If you wish to have a group of this little beauty in your tank, introduce all the Orange Line Chromis fish at a time so that it gets along well with each other at the time of acclimatizing and lessens the territorial behavior.
