Siphamia is a genus of cardinalfishes native to the Indian and Pacific oceans. Several of these species are commensal with various species of sea urchins. Cardinal fishes are from the family Apogonidae, of ray-finned fishes. Small in sizes, usually around 8-10 cm. Cardinal Fishes are a unique fish as it is the Males that carry and brood the Eggs. Usually, the Female will release her egg mass near the chosen Male and after the Male fertilizes the eggs, he will take them into his mouth to carry them during the incubation period, until the fry are ready to hatch. As he incubates the eggs the male Cardinal Fish will open its mouth to rotate the egg mass from time to time, to keep them clean and aerated. At times it will partially expel the eggs before sucking them back in. It is estimated that up to 30 per cent of the eggs are accidentally eaten. During this incubation period, the Male are unable to hunt/feed.
Found in the Indian, and Pacific Oceans; they are chiefly marine, but some species are found in brackish water and a few are found in fresh water. Some species swims among Black Sea Urchin to use as protection.
