Pre-Quarantined for 30 Days! Apolemichthys trimaculatus The Flagfin Angelfish, also referred to as the Threespot Angelfish, is a brilliant yellow with blue lips, a dark blue-black dorsal spot where the head joins the body, and a light tan spot behind the eye. Provide plenty of other hiding places in a 125 gallon tank or larger as the Flagfin Angelfish is quite shy early on and should be the only angel in the tank. Not a good reef dweller, the Flagfin Angelfish is prone to nip at sessile invertebrates (soft and stony corals) and clam mantles. This is a difficult angelfish to keep due to its dietary requirement of sponges. Expert aquarists may have success by providing a mixed fare of sponge-containing frozen angelfish rations, vitamin-enriched brine shrimp, mysis shrimp, a plethora of plant material, and live rock for grazing and hiding.
