The Pearlscale Butterflyfish is another beautiful example why marine Butterflyfish remain perennial favorites among hobbyists. This gorgeous fish boosts visual interest with lively color and eye-catching, graphic patterning. The addition of this stunning specimen in your Fish Only With Live Rock (FOWLR) is sure to make your heart flutter.
True to its namesake, the Pearlscale Butterflyfish has a pearly white body that appears to give off an iridescent glow under the right aquarium light conditions. The brilliant pearly white body color is enhanced by a striking reticulated pattern in contrasting black coloration. Bold punches of orange coloration grace the anterior dorsal and anal fin area up to the peduncle as well as portions of the caudal fin in sickle-shaped bars. Highlights of yellow coloration gracefully trace the tips of the dorsal fin for a truly elegant effect.
The Pearlscale Butterflyfish is part of the “xanthurus complex” consisting of lookalike species with similar latticed pattern. The Mertensii Butterflyfish is a great example of a lookalike. The Pearlscale Butterflyfish is distinguished by a white-rimmed, dark oval spot located slightly askew behind the eye band. Also, upon careful observation, the Pearlscale Butterflyfish has a true reticulated (net-like) or crosshatch pattern while the lookalikes have a distinct chevron or V-shaped pattern.
House the Pearlscale Butterflyfish in a 70-gallon or larger aquarium with other peaceful fish and others of the same species, if all were introduced into the tank at the same time. Similar to other Butterflyfish, the Pearlscale Butterflyfish may require extra “TLC” when first acclimating to the home reef aquarium. The diet of the Pearlscale Butterflyfish should include various meaty preparations including frozen, freeze-dried, fresh or flake food. Also provide regular vegetable food source and vitamin-boosting supplements.
