Dwarf Marine Angelfish Care Sheet

Developed with and approved by a qualified veterinarian.

dwarf marine angelfish

This care sheet covers a variety of dwarf marine angelfish, including:

 

Overview

Centropyge bicolor, Centropyge tibicen, Centropyge acanthops, Centropyge bispinosa, Centropyge flavissima, Centropyge ferrugata, Centropyge argi, Centropyge loricula, Centropyge multicolor, Centropyge eibli

 

Dwarf marine angelfish, with their striking coloration and vivid patterns, are best kept in fish-only aquariums; however, they are compatible with a wide range of marine species. These fish are native to the warm waters of the Pacific and Indian Oceans, Caribbean and Red Sea. It is highly recommended to maintain caution if keeping them in reef aquariums, as they are prone to nip at stony corals, soft corals and clam mantles. Dwarf marine angelfish are semi-aggressive and cannot be kept with their own species (unless they are a mated pair) or other dwarf angelfish species. These personable and alluring fish make a great addition to an underwater marine oasis.

 

Typical appearance and behavior

  • Dwarf marine angelfish come in beautiful and vibrant colors, including yellow, purple, orange, red, black, white and blue
  • They are usually mild-tempered but can be territorial and will become aggressive when breeding
  • Live rock is a great addition to their aquarium for providing hiding areas— they will also nibble the algae and sponge growing on it in between feedings
  • They start life as female and sometimes change to male under certain circumstances
  • Dwarf angels can be sensitive to copper

Building your habitat

  • Water health - Provide proper filtration to ensure optimal water quality to help maintain health. Moderate to strong water circulation, based on species, should be provided to mimic water currents found in the dwarf marine angelfish's natural habitat. Stable water quality (pH, ammonia, nitrate, nitrite) and water temperature are critical to the health of aquatic life. If you are unsure of your water quality, bring a sample to Petco for free testing. The addition of a protein skimmer can aid with maintaining great water quality and high dissolved oxygen levels. An aquatic heater should be used to stabilize water temperature, ensuring it does not fluctuate more than +/-2 degrees in a 24-hour period. The specific gravity should remain stable. Do not allow specific gravity to fluctuate more than +/-0.001 in a 24-hour period.
  • Décor- Provide rock and décor for hiding places and plenty of room for movement.
  • Live rock can provide a natural food source while also enhancing biological filtration.

 

 

Feeding

A well-balanced dwarf marine angelfish diet consists of:

  • A variety of flakes, pellets, freeze-dried and frozen foods
  • Commercial algae sheets

 

Things to remember when feeding dwarf marine angelfish:

  • Feed small amounts 2 to 3 times daily, no more than fish will eat in 1 to 2 minutes
  • Thaw frozen food before feeding

 

 

Dwarf marine angelfish care

Maintaining great water quality with regular water changes and adequate filtration is important to help keep your dwarf marine angelfish healthy

  • Daily: Check filter, water temperature and other equipment
  • Weekly: Test water quality at least once a week
  • Weekly to monthly: Change 10–25% of the total volume of water every two to four weeks, or as needed; change filter media monthly

Avoid overcrowded conditions; this is a major cause of stress and disease
