Data sheet: Valenciennea puellaris (Orange Spotted Goby)


Scientific Name:  Valenciennea puellaris
Common Name: Diamond Goby or Diamond Watchman Goby or Orange Spotted Goby
Taxonomic Classification
Phylum: Chordata
Class: Actinopterygii
Order: Perciformes
Suborder: Gobioidei
Family: Gobiidae
Genus: Valenciennea
Species: V. puellaris
Description: This small fish has an elongated body length of 14 cm in nature, while in an aquarium it usually does not exceed 8 cm.

Coloring: The body is whitish and characterized by a large number of orange dots and on the head there are points of blue iridescent color.
Behaviour: It’s a monogamous fish, rather shy and always in the seabed where it lives almost always in pairs. It passes most of the time to aspirate and expel the sand from the mouth by feeding nourishment, in the form of small organisms and helping to keep it perfectly clean.
Sexual Dimorphism:  The male has the first radius of the elongated and filiform front dorsal fin.
Habitat: In nature it prefers marine environments with sandy areas, depths of 2 to 30 meters, but we can find it up to 80 meters.
Temperature:  22-26° Celsius   pH:  8.1-8.4   Water Hardness: dKH 8-12

Tips for breeding:  It is not advisable to put it in aquariums with DSB since continually wiping the sand up to several centimeters deep and destroying the bacteria needed by the DSB.

Feed: Despite the fact that Valenciennes spend most of their time sifting the sand in search of food, it is good to integrate with a carnivorous diet consisting of a variety of fresh or frozen shrimp, Artemia (Brine Shrimp) enriched with vitamins and uncooked table shrimp. You must be careful to nourish enough so it should be fed at least twice a day.
Diffusion: Indo-Pacific: from Red Sea and east African coast throughout the East Indian and Indian Ocean eastwards to Samoa, noth to southern Japan, south to Australia (Great Barrier Reef) and New Caledonia.
Swimming Level:  The locomotion is diodontiform so propels the fish propagating undulations along large pectoral fins, like in the Porcupine fish.
Difficulty: Moderate
Riproduction: They may reproduce in the home aquarium. The male / female couple places the fertilized eggs on the upper surface of their den. The male keeps the nest as the eggs are growing. In 3 to 4 days the larvae should open and become pelagic (released in the currents). It can be quite challenging to feed larvae with very fine foods (plankton) that they need to develop.
Extinction risk:  Minimum risk.
