The **Frost Fin Cardinal** (Ostorhinchus hoevenii), commonly referred to as the Frostfin Cardinalfish, is a striking and delicate species found in the Indo-Pacific waters. This small fish is known for its translucent body with a yellow or brown tint, a yellow face, and distinctive white tips on its dorsal fin, which is the origin of its name. Typically inhabiting reefs and lagoons, these fish are often spotted near crinoids, sponges, and anemones, using these structures for both protection and hunting.

In aquariums, **Frost Fin Cardinals** are peaceful and thrive in groups of three or more. They are quite hardy and flourish in a well-maintained tank with ample live rock and hiding spots. As carnivores, their diet should mainly include meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood. Their small size and gentle nature make them ideal for nano reefs and community tanks, adding elegance and movement to the aquatic environment. With proper care, these captivating fish will thrive and provide endless enjoyment for their keepers.
