Fin Pygmy Angel
The Cherubfish or Pygmy Angelfish Centropyge argi are beautiful little fish. This wonderful dwarf angel has all the good looks of its larger cousins, making a great substitution for a large angelfish for those who don't have 200 gallons of tank space. With a deep blue body, yellow or orangish face, and blue rings around its eyes, the colors of the Cherub Angelfish are rich and vibrant similar to the Asfur, Maculosus, and even Bluegirdled Angelfish. You can get the same color combo in a "fun size" for your smaller tank.
Cherub Pygmy Angelfish are intelligent, active, and hardy as well. Look for a specimen that will take an aggressive stance, such as a raise dorsal fin, and pay rapt attention as you approach the tank. If it does dart into a cave, it should come right back out to size you up promptly. Their color should be rich, not faded, and they should be very interested in their surroundings and very difficult to catch.
This Atlantic Pygmy Angelfish spends a good amount of time hiding from predators in the wild, so plenty of hiding spaces will make them happy. These fish favor an established reef environment with plenty of nooks and crannies to graze for food. These are very pugnacious little fish, so house Pygmy Angelfish with more aggressive tank mates.
