Kamaka Rainbowfish
The Kamaka rainbowfish was discovered in the Kamaka Lake on the island of Irian Jaya (Indonesia). These beautiful blue and purple hued fish are now bred in Florida where we source some of our rainbows, including the Kamaka. Kamakas are larger, reaching about three and a half inches, and they are a peaceful schooling fish, great for planted and mid-size community tanks.

I added a group of Kamaka rainbowfish to my 10-gallon planted tank. They are vibrant with beautiful blue and purple hues. They stay calm and don’t bother other fish. Easy to care for and look stunning in the water.

The fish arrived healthy and active. They form a nice school and blend well with my tetras and dwarf corydoras. I appreciate the clear description of their peaceful nature.

Great addition to my aquarium. The coloration is striking and they seem to thrive in the moderate lighting and soft substrate. I’ve kept them for three months and they’re still active and happy.
