Brachygobius aggregatus – one of the smallest fishes of the World

6. June 2011

All species of bumblebee gobies (Brachygobius) are small or very small fishes. The debate which is the smallest fish of the world (and coincidently the smallest vertebrate of the world) is still going on; however, it is quite difficult to decide, whether it makes sense to debate about differences of tenth of millimeters in live organisms. May this be as it wants: we are proud to present to you one of the smallest species of fish at all, which we were able once more to import from Vietnam: Brachygobius aggregatus.

The males of this tiny bumblebee goby become (at least in the wild) about 10 mm long, females 15 mm. It may be that they grow a little bit larger under aquarium conditions, but this does not matter at all.

Brachygobius aggregatus is a freshwater goby and very easy to keep. It is absolutely undemanding regarding water chemistry. Medium hard water and a pH around 7 may be ideal. The water temperature may be between 18 and 28°C. Fishes of that size are best fed with live brine shrimp nauplia (Artemia). Of course they feed also happily on any other type of live and frozen food, but live food is often difficult to obtain and frozen food difficult to dose. Thus the easy to breed brine shrimp nauplia are the best choice. It is no problem to feed the Brachygobius aggregatus exclusively with this food.

For our customers: the animals have code 407101 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Brachygobius: from ancient Greek, means “short Gobius”; Gobius is another genus of goby. aggregatus: Latin, means “aggregate”, for the fish were found to be schooling.

Suggestion of a common name: Mekong dwarf bumblebee goby, for there is a scientific investigation going on, whether the Mekong species (which we have currently imported) is really identical with B. aggregatus, which is described from the Philippines.
