Yellow Cardinalfish

The Yellow Cardinalfish, also known as the Yellowstripe Cardinalfish or Yellowstriped Cardinalfish, is a popular species in the aquarium trade. They have a yellow body with a black spot on their dorsal fin. They can reach up to 3 inches in length and are relatively easy to care for in a reef aquarium.

In the wild, Yellow Cardinalfish are known to feed on small crustaceans and plankton. In an aquarium setting, they can be fed a variety of foods including frozen or live brine shrimp, mysis shrimp, and other small meaty foods. It's recommended to feed them multiple times per day in small amounts.

Determining the sex of Yellow Cardinalfish can be difficult as there are no external differences between males and females. One way to potentially differentiate them is by observing their behavior during breeding. Males may be more aggressive and territorial during this time.

Yellow Cardinalfish are known to spawn in captivity. They are egg layers and will lay their eggs on a flat surface in the aquarium. Once the eggs hatch, the fry can be fed newly hatched brine shrimp.

Yellow Cardinalfish are relatively hardy and not particularly prone to any specific diseases. However, as with all aquarium species, they can be susceptible to stress-related illnesses if their water quality is poor or if they are not fed a balanced diet.

Yellow Cardinalfish are found throughout the Indo-Pacific, from the Red Sea to the western Pacific Ocean.

Yellow Cardinalfish are generally considered safe for reef aquariums. However, they may be eaten by larger predatory fish.

It's important to properly acclimate Yellow Cardinalfish to their new environment to reduce stress and increase their chances of survival. This can be done by slowly adding small amounts of water from the aquarium to their transport bag over the course of 30-45 minutes before releasing them into the aquarium.
