FAMILY - Acanthuridae SCIENTIFIC NAME - Acanthurus Japonicus COMMON NAME - Powder Brown Surgeonfish SIZE - 8.3" (21 cm) RANGE - Western Pacific MIN. AQUARIUM SIZE - 75 US Gal. (284 L) FOODS AND FEEDING - Varied diet of mostly vegetable matter, dried and frozen herbivore foods, marine algae, blue green alga spirulina, pieces of zucchini, broccoli, leaf lettuce and sushi nori (dried seaweed). Feed 3 times a day. AQUARIUM SUITABILITY - 6 REEF COMPATIBILITY - Generally safe, will spend most of its time browsing on filamentous microalgae and small fleshy macroalgae. If under fed may nip at large polyped stonby corals. CAPTIVE CARE - Keep only one unless a very large tank is used over 180 US Gal. (681 L) where a small group may be kept. Can be aggressive if crowded, provide plenty of swim room, and a selection of herbivores fare. Do not mix with more aggressive Acnathurids, provide plenty of hiding places and floating algae during acclimation, this fish can be a finiky eater, ships poorly, and should be acclimated carefully. A quiet tank will help in the acclimation process.
