Info
The dwarf perch Pseudochromis fuligifinis was and is only known from the waters around Verde Island, west coast of Mindoro, and Apo Reef in the Philippines and its first description is due to the American ichthyologist Jeffrey T. Williams (Department of Vertebrate Zoology, National Museum of Natural History).
This small dwarf angelfish is not specifically sold in the specialized trade and is shown in the marine encyclopedia for the sake of completeness of the category.
The animals were discovered and collected on a rocky slope with rubble and a sandy plain with silt as well as around an isolated pinnacle with dense coral growth and a steep slope of hard and soft corals.
Similar species: Pseudochromis elongatus Lubbock (1980) from Indonesia and Pseudochromis striatus Gill, Shao & Chen (1995)
Etymology.
The specific epithet "fuligifinis" is a combination of the Latin "fuligo", meaning "soot", and the Latin "finis", meaning "end".
It refers to the sooty appearance of the distal ends of the caudal fin rays.
Dwarf cichlids are bidirectional sex changers, i.e. the sex can be changed in any direction. From birth all fry are female, if two females are put together, then the stronger fish changes to male and changes species specific possibly the colors/fin shape. The sex change lasts from (w to m) 18-56 days. If a mating of two males takes place, then the sex change lasts 52-93 days and it can come over a longer period to massive fights. If there are color variations associated with the sexes, then in the case of two males, the reverted female will take on a cloudy coloration.
Scientifically the sex change is proven in Pseudochromis flavivertex, Pseudochromis aldabraensis and Pseudochromis cyanotaenia in experiments. It can be assumed that the sex change can take place in the same way in the remaining Pseudochromis species.
