The pygmy angelfish, Centropyge argi, also called the cherub fish, is one of the few relatively reef safe angelfish from the Caribbean. Just how reef safe they are might be debated, but because of their small size they don’t pose much of a threat to corals or other non mobile invertebrates. There is a “strain” of these fish that can get up three inches long, but this strain rarely gets 2″ long. These are a beautiful dark purple fish with a splash of yellow or orange around their mouth and operculum. The dorsal and ventral fins are usually lined with a light blue color, but not always.
In an aquarium these fish are very easy to care for and will eat most prepared foods. They will be eating small pellets when they leave our shop, so they should start feeding right away for you.
In the wild they often live in colonies with one dominant male and a bunch of females, but I would not recommend more than one fish per tank . They have been successfully bred in captivity, but only the most sophisticated aquarists have had any luck raising the babies.
Please Note: Any new fish purchased from us or from a local pet store should to be quarantined. All fish from anywhere in the wild can be possible carriers of bacteria and protozoa that can lead to an infection in your system, so we always recommend that you use some sort of quarantine system prior to adding them to your system. If you have a fish only system and can medicate the whole system, you may not need a separate quarantine tank. If you have a reef system that cannot be medicated, a good ultraviolet sterilization system should prevent any kind of disease outbreak. We medicate our system for bacterial infections and protozoans, but because we dont always hold our fish for long periods of time, there is no way to be sure all the protozoan cysts have been killed. A little bit of prevention will save you lots of trouble down the line.
