California Round Ray

The California Round Ray, *Urobatis halleri*, is a fascinating and unique addition to a large marine aquarium. Native to the coastal waters of California, this ray is characterized by its flattened, disc-shaped body and short, stout tail. Its coloration typically ranges from brown to gray, often with subtle spotting or mottling that helps it blend in with the sandy or muddy bottom where it is commonly found.

A minimum tank size of 180 gallons is recommended for a single California Round Ray, with larger tanks preferred to provide ample swimming space and a deep sand bed for burrowing. They are generally peaceful but should be kept with similarly sized, non-aggressive tank mates that will not nip at their fins or tail. Due to their bottom-dwelling nature, it is crucial to provide a soft substrate like fine sand to prevent injury to their delicate underside.

In the aquarium, the California Round Ray will readily accept a diet of high-quality frozen or fresh seafood, such as shrimp, squid, and small pieces of fish. Offering a varied diet will help ensure their nutritional needs are met. They typically reach a maximum size of around 18 inches in disc width. While considered a beginner-level ray, proper research and a commitment to providing a suitable environment are essential for their long-term health and well-being.
