The Yellow Cardinal (Ostorhinchus luteus) can be found among the Indo-Pacific Ocean. Their body is a yellow or beige color with transparent fins. They are found in small schools among reefs or rocky outcroppings, where they hide from predators and search for small crustaceans, which make up their diet. They should be housed in an aquarium with at least 20 gallons with plenty of live rock for them to hide among. They require carnivorous preparations, usually mysis or krill, and should not be kept with larger predatory fish.
