One of the most special features of the red pencil fish is its coloring. As well as the three dark horizontal stripes on a golden background. These increase in intensity depending on the fish. If it is an adult male, the reddish color is even more intense. Like the species of the same genus, it lacks an adipose fin.
These are fish very given to being able to inhabit domestic aquariums together with other species. While you have to be careful in the mating season. As males tend to become very territorial and uncompromising with the rest of the males. They differ very well from females. The males present between the two upper lines a red coloration that begins at the birth of the eye and extends to the tail fin.

They are very sociable fish with each other and they have to live in communes of, around, a dozen fish so they don't feel depressed and can hover around.
