The Vermiculated Angelfish are omnivores, in the wild they eat primarily benthic algae and weeds, but will also feed on sponges, tunicates, and ascidians (sea squirts), and have been observed nipping at stony corals. Provide a varied diet in the aquarium. Offer frozen, flake, and freeze dried foods that also have Spirulina added. They like mysis shrimp, and shredded fresh or frozen shrimp. They will also eat filamentous algae and diatoms in the aquarium. To help get this angelfish to feed when first introduced it is a good idea to have a large crop of algae, including caulerpa or similar macro-algae. It is not uncommon for this genus of angelfish to go about a week without eating anything you have to offer. Try a freshly opened clam or mussel or live feeder mysis or brine shrimp to initiate a feeding response. Keeping the tank area quiet so the angelfish comes out to feed is also important. Feed 3 times a day, and only less if the aquarium has plenty of algae growth.
