Stonogobiops nematodes és una espècie de peix de la família dels gòbids i de l'ordre dels perciformes.
Stonogobiops nematodes, the Filament-finned prawn-goby, the Antenna goby, the high-fin goby, the red-banded goby, the high-fin red-banded goby, the striped goby, the barber-pole goby, or the black-ray Goby, is a species of marine goby native to the Indian Ocean and western Pacific Ocean from the Seychelles to the Philippines and Bali.[1]
Adult fish can grow up to 6 centimetres (2.4 in) in length, with the striking pointed dorsal fin becoming more raised and pronounced in adulthood. This elongated fin is the most obvious distinguishing feature between the black-ray goby and its close cousin, the yellow snout goby (S. Xanthorhinica). The fish are coloured with four diagonal brown stripes across a white body, and a distinctive yellow head.
It is almost impossible for anybody less than a specialised expert in the specific field of these types of fish to discern differences between males and females of the species.
This goby inhabits sandy or sand-rubble bottoms adjacent to reefs at depths of from 15 to 25 metres (49 to 82 ft). It is one of several species that form commensal relationships with Randall's pistol shrimp (Alpheus randalli).[1]
This species shares a burrow with its shrimp partner. The goby has much better eyesight than the shrimp, and, as such, acts as the watchman for both of them, keeping an eye out for danger. The shrimp spends the day digging a burrow in the sand in which both live. Burrows usually measure up to one inch in diameter, and can reach up to four feet in length. The two animals maintain continuous contact, with the shrimp placing one of its antennae permanently on the goby's tail. When danger threatens, the goby will make continuous flicks of its tail, warning the shrimp there is a predator nearby, and the shrimp will remain safely in the burrow. If the danger reaches a certain level, the goby will dart into the burrow after the shrimp.
At night, the goby will go into the burrow, and the shrimp will collapse the entrance to close it off. The burrow is exited the next day by the goby blasting its way out and collapsing the burrow. The shrimp then spends the next day laboriously rebuilding the entrance to the burrow. Both animals have also been known to share food with each other.
When the goby catches food, it will often give a portion of it to the pistol shrimp, through a somewhat similar process of a mother bird regurgitating food to her chicks. This way, the shrimp and the goby are kept well fed. Sometimes, if the shrimp is not kept well fed, it will resort to killing the goby.
In the wild, most burrows are shared by male and female goby pairs, with their respective shrimp partners, and the female goby will use this burrow as a nesting site to lay her eggs.
The obvious benefits to both organisms of this symbiotic relationship make the interaction a form of mutualism. Here is an interesting example of this. The other fish is a dartfish (genus Ptereleotris). These fish are often found as unwelcome but ignored guests sharing the burrow with goby and shrimp.
This goby is in high demand for home and hobby marine aquaria due to its beautiful colouration, docile nature and interesting interaction with symbiotic shrimp. This type of goby is the most common Stonogobiops species to show up in the marine trade, but is still quite rare.
This fish is very docile and poses almost no threat to any other stock inhabiting a typical marine aquarium. This passiveness makes it a perfect tankmate for delicate species like sea horses or pipefish. In fact, it is in reality quite shy, and when first introduced into an aquarium, may take up to several weeks before it is bold enough to leave its hiding place, or bolt hole. While this fish can display aggression towards other tank inhabitants by opening its mouth and "yawning" at them, this is mostly show, and the goby will quickly turn tail and hide if confronted.
The goby will spend most of its time hovering about two inches above its bolt hole, searching for scraps of food in the water column. If scared or startled, it will slowly retreat towards its hole. If the danger does not go away, it will dart inside at lightning speed.
Mated pairs of this fish are very rare and difficult to attain. Individual males may fight if placed in a tank smaller than about 50 gallons (~200 litres).
For successful aquarium culture, this fish needs good sand/coral rubble cover for burrow-building and much rock cover; a reef environment is suitable. The recommended minimum tank size is 10 gallons (40 litres), however these fish mainly hide out in burrows all day, and are not active swimmers, making them candidates for smaller "pico" aquariums. (Aquariums 4 gallons and under.) The water specific gravity should be 1.020 - 1.025, with a pH of 8.1 - 8.4; water temperature at 72 - 78 °F / 22 - 25 °C is ideal, however water temperature up to 80 °F will not harm the fish.
Small meaty foods, such as mysid (sometimes referred to as mysis shrimp) or brine shrimp, along with flake food and algae wafers, spirulina, etc. are all happily accepted. In the wild, these gobies most often feed on zooplankton. The water quality must be kept reasonably high, as with all marine species. A substrate of small-grained coral sand, with larger particles mixed in (preferably four inches or deeper) is ideal for the goby/shrimp pair to make their burrow.

Viiriraputokko (Stonogobiops nematodes) on tokkoihin kuuluva kala.
Viiriraputokko jää noin neljä senttiä pitkäksi. Sen vartalo on vinosti ruskeavalkoraitainen, ja selkäevän etummainen ruoto nousee viirinä ylös. Naama on keltainen ja evissä sinisen sävyä.
Viiriraputokko elää luonnossa Indonesiassa ja Filippiineillä.[1]
Viiriraputokko kaivautuu hiekkaan. Se voi elää samassa kolossa pistooliravun (Alpheus randalli) kanssa. Samassa altaassa voi pitää pariskuntaa, mutta ei kahta urosta eikä muita hiekkaan kaivautuvia tokkolajeja.[2]
Viiriraputokko syö lihapitoista ruokaa.
Le Gobie à filaments (Stonogobiops nematodes) est un poisson marin démersal du genre Stonogobiops appartenant la famille des Gobiidés.
Il est commun en aquariophilie marine.
On le surnomme Gobie à filaments à cause de sa première nageoire dorsale ornée d'un très long filament noir. Son corps, de forme allongée et cylindrique, est blanc, rayé de 4 larges bandes obliques noires qui le strient, la tête est recouverte d'une tache jaune vif qui descend jusqu'à son menton. La seconde nageoire dorsale et la nageoire caudale sont jaune translucide, chacune est ornée de bleu clair. Ses deux grands yeux ronds entourés d'un jaune vif et une bouche protractile. Il fait en moyenne 4 à 6 cm.
Il est originaire de la côte Ouest atlantique, des Bahamas aux Petites Antilles, des îles au large du Venezuela et de l'Ouest des Caraïbes.
Carnivore. Le Gobie à filaments accepte de nombreuses variétés d'aliments, congelés, vivants, lyophilisés.
Le Gobie à filaments est souvent maintenu en aquarium récifal où il est apprécié pour sa physionomie et son comportement particuliers. Il lui faut un aquarium de 150 litres doté d'un décor rocheux et un substrat sablonneux, il sera maintenu seul ou en couple.
Impossible en aquarium.

Stonogobiops nematodes är en art av fiskar som tillhör familjen smörbultar. Som fullvuxen kan den bli upp till 6 cm lång.[1] Den förekommer på 20–30 meters djup i kustnära hav kring Filippinerna, Indonesien och Seychellerna.[1]
Arten är framförallt känd för att leva i symbios med pistolräkan, Alpheus randalli,[1] i en form av mutualism. Fisken har bättre syn än pistolräkan, och varnar räkan då ett rovdjur närmar sig. I gengäld får smörbulten tillbringa natten skyddad i den gång som räkan grävt i bottensedimentet: sedan smörbulten simmat in i gången för natten, stänger räkan gången. Nämnas kan att flertalet andra arter av saltvattenlevande så kallade sandsmörbultar också tillbringar den mörka delen av dygnet nedgrävda, men att de då grävt sitt gömsle själva.
