The Kaudern's Cardinal, also known as the Banggai Cardinalfish or Longfin Cardinalfish, is silver highlighted by black stripes and white spots on the body and long, elegant fins. These fish are bred in and reared in Indonesia and Asia and are hardier than their wild harvested counterparts.

A 30 gallon or larger aquarium with a cave and peaceful tank mates is ideal for this slow and methodical swimmer. Due to its aggressive behavior towards conspecifics, it should not be kept in large groups, though they do like to have a few other Cardinalfish around.

The Kaudern's Cardinal is relatively easy to breed in the aquarium setting. Once spawning has occurred, the male carries the eggs in his mouth to protect them.

The Kaudern's Cardinal should be fed a well balanced diet of meaty foods such as feeder shrimp, marine flesh, bloodworms, and depending on its size, live feeder fish.

Approximate Purchase Size: Small: 1/2" to 3/4" Medium: 7/8" to 1"

Customer Testimonials

Sherry K Hillsdale , WY
This is a nice peaceful little fish. I have a pair and I'm thinking of getting more. When I first added them to the tank, one wedged itself between the glass and a rock and I had to free it, but it recovered. They get along very well with my clownfish and have not bothered my shrimp at all that I can tell. They eat mysis and cyclops, but appreciate live brine shrimp as a treat.

These cardinals are extremely easy to acclimate. No one should have any problems caring for these little guys.
Casey Guntersville Guntersville , AL
Wonderful active fish. Mine were eating straight out of the bag. I ordered 3 and all made it but 2 have paired up and left the third out of the group but the third has plenty of room so no fighting has happened. Highly recommend these for anyone.
Marie C Oakley , CA
I have three of these little fish. It took a couple of weeks for all three to come out of hiding, but now they come to the front of the tank when I walk up. They are doing very well and are quite beautiful close up.
