The Hawaii Helfrichi Firefish is also commonly known as Helfrich's Dartfish, or Mano'o-sugale. Since at times, the Hawaii Helfrichi Firefish becomes territorial especially towards other firefish unless introduced to a tank simultaneously. Therefore, it is best to house the Helfrichi Firefish with docile fishes and passive fishes. It is very good at jumping, and requires a tight fitted tank to avoid any unnecessary accidents. The Helfrichi Firefish doesn?t bother any corals or sessile invertebrates, and is considered a reef safe species. It thrives well in a temperature range of 72-78 degrees Fahrenheit and pH of 8.1-8.4. The Hawaii Helfrichi Firefish eats meaty foods, such as frozen Cyclops, frozen fish eggs, preparations for marine carnivores and even flake food. It should not be combined with the dottybacks, damsels (including larger anemonefish) pygmy angelfish, hawkfish, sand perches and wrasses. The Helfrich?s firefish sometimes suffers from swim bladder disorders. It has an elongated first dorsal spine that ??jumps?? up and down, and is suggested to keep with enough rockwork. The Hawaii Helfrichi Firefish fish loves to hang in and therefore we advise you to keep a few live rocks, crevices and overhangs to set a realistic feeling to the fish.
