Care
The Torpedo 'Goby' is a peaceful shoaling dartfish known from the relatively shallow waters of bays, lagoons, and outer reef slopes. Here these pretty, elongate fish gather in large aggregations, hovering above the substrate amongst the current-swept waters to feed on zooplankton. A mated pair will occupy the same burrow, but if a large shoal is startled or when danger approaches, many individuals will hastily retreat or 'dart' into the same refuge together. The aquarium should be mature and offer plenty of swimming space. There should be ample nooks and crannies amongst the rockwork for the fish to hide in, as well as a fine sand substrate into which they can bury at night or when startled. As an especially gregarious species, it is important that a good sized group (of at least 5 individuals) are kept together, and these should be added to the aquarium simultaneously. Tankmates should be very peaceful as Torpedo 'Gobies' are of a somewhat nervous disposition and will not cope well with boisterous companions; indeed, it is most important that they are not intimidated out of feeding so observe carefully. Anthias, blennies, cardinalfish, dragonets, firefish, gobies, and grammas would all work well. Wherever possible, site the tank in an area that does not receive constant foot traffic, and ensure that all illumination switches on and off gradually rather than suddenly, as these fish are so easily spooked. Due to their fast metabolism (and consequent requirement of food offerings several times per day), decent filtration and areas of brisk water movement are essential. Ensure that the tank has tight fitting coverslides and no escape holes where equipment feeds into the aquarium, as these fish are expert jumpers. May also be seen on sale as the Blackfin Dartfish.
Feeding
In the wild, this species is constantly on the lookout for food, taking zooplankton from the water column. Due to their fast metabolism, they require feeding in small amounts several times per day (i.e. at least 4 times) if they are to maintain good health. Offer a variety of fine meaty foodstuffs such as Mysis shrimp, vitamin-enriched brineshrimp, finely chopped krill/prawns etc in addition to zooplankton preparations (containing copepods and rotifers) which are often available in either frozen or refrigerated forms.
Breeding
This species has not been bred in the home aquarium. However, it is likely to spawn in a similar manner to that of its close relatives, so please see the breeding section of the Shotsilk 'Goby' (Ptereleotris zebra) profile for further information.
