Kamaka Rainbowfish Diet

The Kamaka rainbowfish is an omnivore that feeds primarily on worms, insects, mosquito larvae, and daphnia in its natural habitat.

In captivity, you can feed them a variety of live and frozen foods such as brine shrimp, bloodworms, and daphnia.

Kamaka Rainbowfish Breeding

The Kamaka rainbowfish are easy to breed in captivity. However, you need to provide them with the proper environment to ensure a successful spawn.

Some things you need to take into consideration are:

  • Provide them with a separate breeding aquarium
  • Fill the breeding tank with 75% mature tank water and 25% dechlorinated freshwater
  • Add marbles substrate and plenty of fine-leaved plants, spawning mops, or Java moss clumps
  • Install a small air-driven sponge filter
  • Introduce a healthy pair to the tank

After you set up the breeding tank, the male will display the mating stripe on his forehead to the female.

Then, the male will start swimming in front of the female to guide it over the plants.

After that, the female will deposit the eggs in a weedy area, where the male will fertilize them.

Within 7-10 days, the eggs will hatch into the living fry. 

Once they are free-swimming, you should prevent the parents from eating the fry by moving them to a different tank.
