Centropyge argi

Centropyge argi, commonly known as the Pygmy angelfish, is a small angelfish. They've the typical Centropyge body shape, with a dark blue almost purplish base colour and a yellow to orangish head. They’ve an electric blue rim on their dorsal, anal and pelvic fins.

Like all other angelfish it's hermphroditic and the most dominant fish will turn into a male when there is no other male around. These fish are quite peaceful but be careful combining them with fish a lot smaller or larger and other (dwarf)angelfishes. Although dwarf angels are certainly more likely to be reef safe compared to their larger relatives and thus seen more often in reef tank, they're always a risk. C. argi is considered one of the friendliest and most reef safe dwarf angels, but even here, individuals are known to harass certain corals (usually LPS or clams) to the point they can't be combined anymore. Keeping them well fed seems to reduce the risk, so make sure to feed them a proper varied diet of algae and meaty foods to make them really happy!
