Valenciennea strigata and Valenciennea puellaris:card, price, features, nutrition, reproduction and info onValenciennea wardiisValencienna decorates.
Almost all such fishValencienneathey are recommended to keep the sand clean: with the mouthparts, in fact, they suck up the sand and reject it, retaining zooplacton and other organic particles. In practice, these are very effective but also delicate cleaners and do not get along well with aquariums that are excessively rich in corals.
Just like theGobidon okinawae, even the genreValencienneabelongs to the Gobiidae family. The species ofValencienneathe most sought after, to be added to the reef marine aquarium, are:
- Valenciennea strigata
- Valenciennea puellaris
- Valenciennea wardi
Less known, but equally appreciated are the species:
- Valenciennea helsdingenii
- Immaculate Valenciennea
- Valenciennea longipinnis
- Valenciennea muralis
- Valenciennea parva
- Valenciennea persica
- Valenciennea randalli
- Valenciennea sexguttata
Although these species have different liveries and appearance, almost all have one characteristic in common: they are monogamous and suffer from loneliness.
If you have decided to enter a Valenciennea in your marine aquarium, add it in pairs. The problem I found is that there are mainly male specimens on the market, so who wants to try onebreeding in captivity(almost impossible) will have to face a first difficulty: that of finding a female.
If not added in pairs, the Valenciennea fish may suffer from loneliness and have lower life expectancies.
Valenciennea strigata: card
Origins: Pacific Ocean, from East Africa to the Tuamotu Islands. Japan (north coast and south coast), Australian south coast and Lord Howe Island.
Habitat: it populates the sandy areas, especially along coral reef slopes. It is usually found at very different depths (from 3 to 25 meters!) Where it lives in burrows and feeds by sifting the sand to capture small invertebrates and organic material.
Description: it has a pale gray body with a yellow head, characterized by a curved light blue bar that starts from the eye and other similar bars that streak it along the gill.
Valenciennea puellaris: profile
Origins: Pacific Ocean, from the Red Sea to Samoa, north and south coasts of Japan and in the southern area of the Great Barrier Reef.
Habitat: inhabits sandy areas, slopes or bottoms of coastal lagoons. It is found at depths between 2 and 12 meters. It lives in burrows sifting sand to capture small invertebrates and organic matter.
Description: it has a pale gray body, with characteristic longitudinal orange features along the whole body, on the head it has light blue stripes (but they can also be white). For its maintenance in the aquarium, what has been seen for the other species ofValenciennea.
Valenciennea Wardii: profile
Origins: Indo-Pacific Ocean, widespread almost everywhere.
Habitat: it inhabits sandy and silty areas, generally little affected by the current such as coastal bays, protected lagoons. It lives at depths between 5 and 20 meters, digs burrows in tunnels and feeds by sifting the sand as well as the Valenciennea Puellaris and the Valenciennea strigata and other species of this genus.
Description: has a more striking body. White with brown-orange bands, the dorsal fin has a typical black and white spot. The garment has a celestial longitudinal streaks. For the maintenance of theValenciennea Wardiithe same applies as seen for the other species.

Valenciennea in the aquarium: things to know
Before introducing a specimen of this genus into the aquarium, you must ensure that your aquarium is well established and mature, so as to guarantee a rich benthic fauna in the bottom.
It is not possible to introduce it in aquariums with coarse-grained substrates: the sand must be fine-grained (1 - 2 mm).
These fish have a very peaceful temperament and should not be placed in aquariums where there are aggressive fish with fins or weevils (angelfish, triggerfish, scorpion fish…).
THEValenciennea fishthey need burrows and will normally look for holes and crevices where to hide, so they must not lack a safe rock, otherwise they will tend to make a den by digging sand under the rock: make sure your aquarium is very stable, consider cementing or gluing live rocks!
Like many genera of the Gobiidae family (also like the Gobidon Okinawae), these species also suffer from stress and can jump out of the tank ... Keep an eye on the fish and monitor it carefully especially in the first phase of insertion into the tank or if you make any changes drastic in the aquarium.
As for nutrition, a well-ripened tank is an excellent starting point. These fish sift the sand, (they collect it in large mouthfuls!) And then chase it out of the gills, keeping only the edible things (zooplankton and small invertebrates).
It is necessary to give food: finely chopped fish, krill, shrimp, scallops, squid ... but also clams or live copepods. In captivity they also adapt to dehydrated foods (shrimp pellets!) But not all species respond well to feeding in captivity. In this case the only guarantee is given by the administration of worms of the genus Lumbriculus variegatus.
Thepriceof these fish depends a lot on the retailer and the period.
