Males display vibrant neon red to red-orange and blue coloration on their bodies and fins, particularly while competing with other males. The second dorsal and anal fins of males become very extended and fan-like with maturity. Females are typically smaller with shorter fins, but still usually display vibrant coloration. 

They are egg scatterer. You’ll have to find a separate tank for spawning, It should have dim lighting and bunches of thin-leaved plants such as Java moss or some other spawning material. Adult species may eat the eggs anytime they have a chance to do this, so remove them from the tank right after the spawning is over. The eggs incubate for 24-36 hours, the juveniles start swimming in 3-4 days after this.
