Shape Characteristics

There’s a reason they’re named “Rainbowfish.” This fish will attract your attention with its colorful. The Boesemani Rainbow Fish is actually a species with two halves. Their rear part consists of warm colors such as red, orange, or yellow. Their heads, on the contrary, are blue, green, or light purple.

Although they cannot change color, each fish can control their color intensity. This often reflects mood or health. Dark colors may indicate the fish is ready to mate, but pale colors may signal illness or stress. The environment and external interactions can also affect their color change.

Their body is oval in shape, with the caudal fin sticking out at the end. The rest of the fins are relatively small and do not extend beyond the body. The dorsal and anal fins, respectively, above and below the body, run along the posterior half of the body and stop at the caudal fin. Their heads are narrowed to a point in front. They have small mouths and big eyes.
