Lamarck's Angelfish

A genuinely reef-safe swallowtail angel — silver-white streaked with clean black horizontal lines and trailing tail filaments, hovering out in open water rather than grazing the rock. Unlike the coral-nipping dwarf and large angels, Genicanthus feed on drifting zooplankton, so they leave corals, clams and inverts alone. It is peaceful and non-confrontational, best kept singly, as a male-female pair, or one male with a small harem of females; never house two males or two Genicanthus species together. Active and long, it wants open swimming room and can jump, so use a lid.
