Overview
Valenciennea wardii, known as Ward's tiger goby, is a marine fish of the family Gobiidae. It was described by Playfair in 1867. It is a sand-sifting goby recognised by a pale body marked with brown bars and a blue-white band below the eye.
Taxonomy
- Family: Gobiidae
- Genus: Valenciennea
- Scientific name: Valenciennea wardii
- Authority: Playfair, 1867
Habitat
According to FishBase the species is extremely rare and known from widely scattered localities across the Indian Ocean and western tropical Pacific. It is reef-associated, occurring over sandy areas of shallow lagoon reefs, coastal bays and inner reefs on silty slopes, recorded at 5 to 88 m and typically 5 to 20 m.
Tank requirements
- Minimum tank volume: 200 L
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- GH: 8-12 °dGH
- Maximum size: 15 cm SL
- Lifespan: 3-6 years
Diet
Valenciennea wardii is a carnivore. Like other members of the genus it feeds over sand bottoms; a fine sand bed and feeding about twice daily support its natural foraging.
Compatibility
This is a peaceful, bottom-dwelling goby that occurs in pairs in the wild. It suits reef tanks with calm tank mates such as clownfish, cardinalfish and wrasses, and should not be kept with predators.
Breeding Valenciennea wardii (Ward's Tiger Goby)
Overview
Valenciennea wardii (Playfair, 1867), Ward's sleeper, is an Indo-Pacific sand-sifting goby that FishBase describes as extremely rare and known from widely scattered localities in the Indian Ocean and western tropical Pacific. It reaches 15.0 cm SL over a depth range of 5-88 m and occurs in pairs on sandy lagoon reefs and deeper silty slopes. Its reproduction is documented mainly through the shared biology of the genus Valenciennea.
Sexing
FishBase records that the species occurs in pairs, consistent with the monogamy seen across Valenciennea. The sexes are not easily distinguished externally, so a pair is best obtained as two fish that already share a burrow, with a ripening female showing a fuller abdomen before spawning.
Conditioning
Like its congeners this sand sifter takes small benthic invertebrates and is placed at an estimated trophic level of about 3.2. A pair is conditioned over a deep, fine sand bed that supports continuous sifting, alongside regular meaty feeds to build spawning condition.
Breeding Setup
A spacious system with a deep sand bed and rock for burrow construction is needed; the knowledge base lists a minimum volume of 200 L. Parameters are temperature 24-26 degrees C, pH 8.1-8.4 and moderate flow. The pair excavates burrows that serve as both refuge and spawning chamber.
Spawning Behavior & Trigger
Following the Valenciennea pattern, the pair spawns inside a burrow and attaches a demersal egg mass to the burrow ceiling. A settled, well-fed pair with secure burrows is the practical prerequisite; no distinct external trigger is documented for this rarely studied species.
Egg & Fry Care
As in related sleeper gobies, the male tends and fans the eggs in the burrow until hatching while the female maintains the mound that promotes water exchange. The hatched larvae are planktonic, and no reliable aquarium rearing protocol is documented for this species.
Common Challenges
- Sourcing a bonded pair, since the species is described as extremely rare in the wild and the trade.
- Maintaining a deep sand bed and feeding regime suited to an active sand sifter.
- Rearing planktonic larvae, for which no validated protocol exists.
