The Ruby, also known as the Jewel Fish, is a relatively easy fish to keep and breed. The Ruby does not have very strict requirements for water quality, and can grow well in water temperatures of 21-30 degrees Celsius. In addition, it is more adaptable to changes in water temperature and can grow well in both higher and lower (within a certain range) water temperatures. This fish is not food selective, and is willing to feed on both live animal baits and artificial match baits. The ruby fish is not suitable for mixing with other tropical fish because it loves to bite other species of tropical fish, therefore, the ruby must be kept singly.

The ruby is a kind of tropical fish that is relatively easy to reproduce, and when reproducing, it is necessary to choose the ruby that is robust and has the characteristics of this species as the parent fish. The pH of the water used for breeding should be adjusted to 7.0-7.2, the hardness is 7-9 degrees, and the water temperature should be maintained at about 28℃. Then a large and flat pebble is placed at the bottom of the tank for the parent fish to lay eggs. Finally, put a pair of selected parent fish (the female should be more beautiful than the male during the breeding period) into the breeding tank. One point to note here is: to select the male and female fish in heat at the same time as the parent fish, if the male fish has been in heat, while the female fish has not yet come into heat, the male fish attacked the female fish, the result is that the female fish is either dead or injured. Fertilized eggs usually hatch in about 72 hours, and the young fish can swim freely on the fourth day after hatching.
