The Western Blue Devil is an interesting species that is not commonly kept in a reef-style aquarium, but it has been reported to be safe with corals and anemones. Despite this, it should be kept alone in all but very large aquariums with plenty of live rock. As a nocturnal species, it also requires hiding spots to provide shelter from bright lighting, being most active at dusk. It is important to note that the Western Blue Devil will eat all small fish and shrimp, so tank mates should be chosen with this in mind. Additionally, its diet should be supplemented with plenty of high-quality frozen meaty foods. With the right care and environment, the Western Blue Devil can be a unique and beautiful addition to any aquarium.

This species of fish is known to be very finicky when it comes to feeding. Therefore, when first introducing this fish to the aquarium, live saltwater feeder shrimp should be used to entice it to eat. Once it has adjusted to its new environment, it can be fed more meaty foods and frozen preparations 2-4 times weekly. This can help ensure that the fish receives a balanced diet and stays healthy. Additionally, it is important to monitor the fish’s appetite and adjust the feeding accordingly. By doing so, you can ensure that your fish is getting the nutrition it needs.

As a general rule, we recommend between 5 and 7 inches in size when purchasing a monitor.
