Blue Angelfish (Holacanthus bermudensis)


The Blue Angelfish, also known as the Common Angelfish, are a type of angelfish that changes color with maturation.


As juveniles, the Blue Angelfish has a yellow to brown gradient patterned body with bright and pale blue vertical stripes. Their curved anal and dorsal fins are trimmed with blue and their caudal fins are a bright yellow.


Once they mature, their curved dorsal and anal fins morph into angular shapes and are trimmed with blue, orange, and yellow. Their bodies take on a aqua color with yellow scales and they lose the vertical blue striping.


The best housing environment for the Blue Angelfish is a 250 gallon tank with live rock for grazing and multiple places to hide. These angelfish are not the best reef dwellers. They nip at stony and soft corals (sessile invertebrates) and clam mantles, and they are also a bit aggressive towards other angelfish, so it is best to keep them as the only angelfish in the tank.



The diet of the Blue Angelfish should include: meaty foods such as mysis or frozen shrimp, spirulina, marine algae, and high-quality angelfish preparations.
