Paraplesiops meleagris. The Western Blue Devil, sometimes referred to as the Blue Betta, is found in rocky crevasses of the reefs of Australia. It is a beautiful fish that is blue in color with many light blue spots. The anal and dorsal fins are very long, giving this fish a dramatic look. This is a rare find from Australia, and should be maintained in a cooler aquarium. The Western Blue Devil is not commonly kept in a reef-style aquarium, but it is reported to be safe with corals and anemones, however, it will eat all small fish and shrimp. These fish should be kept singly in all but very large aquariums with plenty of live rock. It is nocturnal and requires hiding places to provide it shelter from bright lighting, being more active at dusk. When first introduced into the aquarium, live saltwater feeder shrimp should be used to entice this fish to eat. Once acclimated, it can be fed meaty foods and frozen preparations 2-4 times weekly.
