Blacknosed Butterflyfish

(Johnrandallia nigrirostris)

Johnrandallia Butterflyfish should be added to large well established aquariums with plenty of room to swim. Plenty of rock work should be provided for grazing and hiding. Johnrandallia Butterflyfish are considered hardy, and will generally adapt well in aquariums. Johnrandallia Butterflyfish use their long noses to explore cracks and crevices for food and may pick at tube worms, crustaceans, algae, clam mantles and corals if not well fed. A diet of meaty foods including live fortified Brine and mysis shrimp and black or red worms along with herbivore preparations should be provided. If not readily eating try pressing foods into holes or crevices mimicing their natural feeding habits. Johnrandallia Butterflyfish are considered peaceful and can be kept in groups if added at the same time. Johnrandallia Butterflyfish can be kept with a bit more agressive tank mates but should be added first. These Butterflyfish do prefer a cooler aquarium.
