The basic equipments needed for the cardinal fish growth:

Mouthbrooders breeding care:
Always give a company to the cardinal fishes. When placing cardinal fish couple in the aquarium, see that the fishes are of opposite sex. The breeding is seen in the spring season and the breeding is different from the other fishes.
After the breeding is successful, the female cardinal fish lays eggs and the male cardinal fish carry the eggs in its mouth till the eggs hatch into small cardinal fry’s.
This is a rare case in breeding that male cardinal fish takes care of the fishes and hatch the eggs. Some species of cardinal fishes carry the hatched cardinal fry’s too. Carrying the fry’s for a week develops immunity system.
Once the cardinal fry’s are out of the male cardinal fish mouth, they look exactly like cardinal fishes but in a smaller size. Feed with large quantities of food when the cardinal fry’s are out of the male cardinal mouth.
The big cardinal fishes consume most of the food and these fry’s are left out with no food. So, it’s better to separate these fry’s from the big fishes aquarium for a better growth.
