If your child is one of those that can spend hours and hours just peering into an aquarium and admiring the fish that roam its depths, they are sure to have talked to a friendly angelfish at some point.

Angelfish is one of the most common types of fish seen in an aquarium at people's homes, and not without good reason. There are several different types of angelfish, and each one has a very distinct and attractive coloring that separates it from its fish cousins.

The half black angelfish, pearlscale angelfish, or Centropyge vroliki (named after famous Dutch anatomist Willem Vrolik) boasts a very ornamental-looking exterior, causing it to be a common sight in the aquarium trade.

Native to Australia, Vanuatu, and the Marshall Islands, these fish are known to hybridize with the Blacktail angelfish and the Lemonpeel angelfish, leading to all sorts of exotic patterned fish.

While the half black angelfish (Centropyge vroliki) is not the apex predator, they will not hesitate to feed on clam mantles, Mysis shrimp, and Spirulina (marine algae).

As such, they are often provided with a live rock for grazing in their aquarium. They may seem like dwarf fish due to their size, but make no mistake, the half black angelfish do not get along well with other angelfish.

They don't mind other species of fish like the Bluespine Unicornfish or the Golden Cave Catfish though, so they're a semi-aggressive aquarium companion.
